Mastering the Pentatonic Article 3 – BB King 6th and the BB Box
The Pentatonic Scale is the holy grail for guitarists. It’s easy to play and it sounds amazing.
This series will show you how to get the most out of our favourite scale, and how making small modifications will get you sounding like the pros and their signature sound.
In this article we will look at BB King’s unique note choice when soloing, and articulation techniques synonymous with the blues legend. Below is the A minor pentatonic scale.
Here are the notes and intervals of the scale:
A(root) C(m3) D(4) E(5) G(m7)
BB King 6th and the BB Box
BB played these notes to great effect. But he also added different ones and incorporated them into an incredibly user-friendly “box” to solo over dominant blues progressions. It’s called the “BB Box” (see below).
On the B & E strings, you can see familiar Minor Pentatonic notes (plus the 2nd). What gives this box the specific BB “flavour” is the use of the 6th on the G string, a note not found in the Minor Pentatonic. This box is also very versatile as you can play the Major 3rd as well with just a small half bend on fret 13. The blue note (b5) can also be added in between fret 10 and 12 on the E string.
This box will give you a brand new set of licks, as this formation of notes isn’t found in your usual pentatonic shapes.
On the right is a BB styled lick using the “BB Box” in A.
BB had his own way of bending notes and using vibrato. His vibrato is incredibly fast and achieved by almost hanging your whole hand off the neck. BB would also make these huge leaps up to the tonic note of the key. These ideas are demonstrated below.
These ideas can also be seen in the opening lick of “Lucille”.

Build Log: Pedal board build
Terry Relph-Knight copyright reserved.
The commission for this guitar effects pedal board build was to build a fairly compact, rugged and portable effects board based around effects pedals the client already owned and regularly used. Both the sequence of effects connections and the layout was to be optimised without the physical order limiting the connection order.
A Pedaltrain Pro Junior was chosen for the base, being both light and strong and available with a tough nylon carry case. Nine volt power is provided by a small and economically priced switching supply, the Diago Powerstation. Rather than rely on plugging the mains power lead into the small two pin figure of eight connector on the side of the Diago, the mains lead from the Diago was wired to a standard 3 pin IEC connector, mounted on a bracket at the back of the Pedaltrain base. Nine volt power distribution is via a 6 way Diago daisy chain cable. For the original board layout with seven pedals the seventh power connection was provided by an extra cable that plugged in to the auxiliary power output on the back of the BOSS Chromatic Tuner.
The pedals were attached to the Pedaltrain base using conventional hook and loop self adhesive Velcro with the hook tape fitted to the Pedaltrain and the loop tape to the pedals.
The only pedal modification was to the VOX Wah Wah. This pedal had been previously restored – cleaned, pedal polished, base re-painted and a new control pot fitted. For use on this pedal board it was fitted with an external 2.1mm power jack, having previously been battery only.

Current value – Can be found on offer for £1,700. Purchased from Wunjo’s for £2,000.
Delivered with a rectangular cream and maroon Fender Custom Shop hard case, including a custom shop certificate and other documentation.
Strung 10 to 52 Ernie Ball STHB
Description – A Fender black guard Custom Shop replica of a 1951 ‘Nocaster’ Telecaster, reliced with all slot screws.
Body – Light swamp ash body in the traditional blond finish. Relic wear under the forearm and around the back edge. The black 5 hole pick guard does indeed appear to be made of a thin (0.0625 inch 1/16) sheet of un-bevelled phenolic material and the top surface is lacquered to make it look blacker and shinier. A small area below the top E string has been rubbed away to simulate playing wear.
Neck – One piece, fat soft V, maple neck with a walnut skunk stripe. Wear through on the lacquer up to the eight fret. 21 thin vintage frets. Headstock carries only the script Fender logo in silver with black outline, Fender Custom Shop V logo on the reverse.
Repair Log Fender Custom Shop 51 Nocaster
Hardware – Kluson style tuners. A single round string tree next to the G tuner. Custom Alnico 3 Tele pickups (bridge pickup has flat magnets). Nickel plated folded thin sheet steel bridge with three brass barrel saddles, 4-40 height screws?. Through body stringing with flat ferrules. Four bolt, chrome plated steel neck plate stamped with the NC77 serial LIMITED EDITION and the Fender Custom Shop V logo. Standard Tele control plate with a three way switch and solid nickel plated brass flat top (slight edge radius) knurled knobs. All cloth wired. Tone and volume controls are modern CTS pots. Unfortunately these pots have no stress relief clip, the pot shaft slides in the collar and is only held in place by the locating post into the middle of the steel clip on cover.
This guitar as shipped from the Custom Shop was originally wired to the ‘51 Nocaster schematic with a 15K (wired between neck and middle on one half of the switch and an 0.05uF cap (wired from the other half of the switch – neck terminal – to ground). These components have been removed and the guitar re-wired to modern Tele wiring by a previous owner.
The original ‘51s had no variable tone control. The wiring offered –
Neck pickup with a set bassy sound (no variable tone control)
Neck pickup with no tone control at all
Both pickups with the second rotary control acting as a blend for the bridge.
The neck pickup has the North of the magnet poles up and the bridge has the South up. The pickups do seem to be arranged for hum cancellation in the middle position.
Centre saddle low E to middle 12 fret 327mm, 325mm high E. 257mm front edge of bridge to middle 12fret. Bridge plate is 3 3/8” long.
Problems – Brought in for noise (hum) and a loose output jack. Guitar occasionally produces loud crackles and hums. Seems related to the tone control.
Work done –
Tightened up the nuts on all the controls, on the switch and on the output jack. Dabbed on some clear nail varnish to help lock the output jack nut in place. Replaced one of the rusted ‘reliced’ pickup screws with a clean screw. Re-bent the cover tabs on the tone controls loose cover, shifted the output jack ground over to the back of the volume control where all the other circuit grounds are. Sleeved the long bare wire on the tone cap. Placed an M3 nut inside the Tone knob as a spacer to stop it scraping on the control plate. Replaced the missing switch tip with a barrel tip (the original barrel tip was included in the case, but the slot for the switch arm was so gouged out that it would no longer fit securely).
Having removed the strings in order to lift the bridge I removed the saddles, sanded them down to remove old string notches and soaked all the screws and springs in WD40 to remove dirt and rust. Also cleaned the bridge plate. With the saddles re-assembled and replaced on the bridge plate I set up the action and intonation.
Diagnostics – Loose output jack. Missing switch tip. Pot nuts are loose. Control plate screws loose.
A quick fret rocker test shows fret 8 is high in the middle and one or two other frets further down the neck are a touch high. Fret surfaces look as though they have been levelled fairly recently, but not re-crowned.
A continuity test showed that the bridge plate and strings weren’t connected to ground. Removing the strings and lifting the bridge plate revealed that the ground jumper between the pickup ground lead tag and its elevator plate was intact. It turns out that all three reliced bridge pickup screws were so rusty they no longer made an electrical connection between the pickup elevator plate and the bridge.
Input jack tip contact seems slack, jacks don’t make a positive insertion. Ground lead from tone cap (cap added by previous owner when the guitar was re-wired to modern wiring) is not sleeved and runs over the top of the volume wiper where it could short out.
The tone control seems loose and repeatedly rotating it fully anti-clockwise often produces loud crackles and hums. Looking closely the steel back cover is loose on its four folding tabs. Ridiculously, the only ground return for the output jack is through a black cloth covered wire that is soldered to the back of this cover. With the tabs to the cover being loose the output jack ground has only a very sketchy and intermittent connection to the guitars circuit ground. Perhaps the 1950’s pots had more reliable connection to ground from the cover, the pots in this guitar are of course modern CTS pots. CTS do seem to have changed to using a thinner, softer steel for the pot casing and the fixing tabs are quite easily loosened through down pressure on the pot shaft.
Along with the bad ground connection to the bridge plate the grounding scheme seems very poor. Fender may have been intending to exactly copy a ‘51 Nocaster, (the Fender shop wiring drawings do show this as how the ground was wired) but in the process they seem to have done some really daft things.
Screws – American guitars have either 4-40 or 6-32 saddle height adjustment screws. The first number indicates diameter and larger numbers greater diameter. The second number indicates thread count – 40 is more per inch than 32.
4-40 is 0.112 inch clearance
6-32 is 0.138 inch clearance
4-40 are smaller screws found in Strat saddles.
So 6-32 is the larger size found in the early Tele 3 saddle bridges.
My DeTemple titanium 3 saddle Tele set has ½ inch long screws in the centre and 3/8 long on the two outside saddles. My Rutters is 3/8 and 5/16.
Bridges like the Wilkinson are metric and use M3 screws. They seem to be all 10mm long.
Black barrel switch tip.
Further work – 20/12/17
The original slot head saddle grub screws stick up and are sharp and uncomfortable under the palm of the right hand. I replaced the original screws (six 7/16” long 6-32 slot head) with two stainless steel 1/4” long 6-32 hex head screws for the high and low E strings and four stainless steel 3/8” long 6-32 hex head screws for the other four strings (1/16” hex key for adjustment).
Article 2 – Carlos Santana – blend Dorian
The Pentatonic Scale is the holy grail for guitarists. It’s easy to play and it sounds amazing. This series will show you how to get the most out of our favourite scale, and how making small modifications will get you sounding like the pros and their signature sound.
In this article we will look at how Carlos Santana adds two notes to the pentatonic to create the latin-blues mix he is known for. Below is the A minor pentatonic scale.
The two notes we need to add are the 2nd (B) and a major 6th (F#). Our scale now looks like this (see right).
These new notes create semitones within our pentatonic scale. This interval is key in sounding like Santana. If you were to add these two notes in both octaves of the pentatonic you would now be playing the Dorian mode, but more on that later!
We will now look at song examples where Santana strides between the pentatonic and Dorian:
Oye Como Va” Intro melody:
The song is in the key of A minor, hence our use of a minor scale. The melody ascends, making full use of the 2nd (B), before falling back to the tonic note. Syncopated (off-beat) notes also give this lick a latin flavour.
“Oye Como Va” Main melody:
Here Santana uses the 6th (F#) on the 7th fret of the B string. He mixes this dorian lick with a classic blues motif in the second bar.
“Evil Ways” Solo: (transposed to Am)
A quintessential Satana lick; starting on the “and” of beat 1 gives the lick a real syncopated feel. The first bar is strict Dorian, followed by a classic blues lick in bar 2.
“Samba Pa Ti” Main melody:
One of Santana’s most famous instrumentals. The following three licks are all taken from the opening section. Here we introduce a new Santana technique of grace notes. These quick notes add another latin flavour. Lick 1 is the opening melody, lick 2 its response, and lick 3 is a turnaround used to get back to chord I.
Repair Log – 1996 Fender Pro Junior valve amplifier
Terry Relph-Knight copyright reserved.
The Pro Junior is a 15W combo amplifier with two 12AX7 dual triode valves and a pair of EL84’s in push pull for the output. The power transformer is rated for 230V and a solid state rectifier produces around +319V for the B+. Note – check if this particular amp has an export transformer with adjustable input taps. Checked and it does, but only for 110V and 230V.
The semi-open back cabinet on this amp is of particle board covered in much worn lacquered tweed. A 10 inch 8 ohm loudspeaker is mounted on a ‘floating’ baffle board with a brown synthetic grille cloth with horizontal baize highlights. Top mounted controls on a chrome plated steel panel with white silk-screen legends – Input jack, volume, tone, power indicator and power toggle switch.
Various problems – Crackling and chronic instability. Also distorted output. Broken handle, and later on a ripped out input jack.
Fender Pro Junior
Work done – When first seen I simply replaced the blown Fender branded 10 inch loudspeaker with a new Eminence Legend 125 and cleaned all the valve bases with contact cleaner. The crackling problems seem associated with the old phenolic bases being fried by the output tubes idling at high dissipation. Later replaced all 4 mini Noval valve bases with ceramic bases and installed an output tube bias adjustment. Set bias to 2.7V (for that particular set of output valves) across one half of the output transformer.
The ripped out PCB mounting input jack was replaced with a floating nylon jack connected via two short wires to the PCB.
At some point the output tubes were replaced with a matched pair of JJ’s and a new handle was fitted.
4 x ceramic mini Noval valve bases – £ 13.44
1 x 50K preset – £ 1.64
Stripboard and wire – £ 2
Parts total – £ 17.08
Later on – A problem with almost no output. Turned out the phase splitter DC balance was completely out of wack. One triode was hard on the other off. This problem was extremely difficult to diagnose. It was eventually found to have been due to leakage currents through dirt on the PCB surface. Cleaned the PCB with isopropyl alcohol and the phase splitter returned to proper D.C. balance.
July 2017 – Latest problem – the amp squeals when flat out. First 12AX7 is microphonic. Swapping the first valve with the second cures the problem. However one of the set of JJ EL84 output tubes is running hot – the red silk screen logo on the valve is burnt brown (and the heater filament flares bright yellow at the pin connection when the amp is turned on !!!!).
Work done – Replaced all the valves with new Electro Harmonix valves.
Mains voltage setting check – The amp appears to be set to 230V and this is the highest primary voltage available.

Article 1 – Eric Clapton; add a major 3rd
The Pentatonic Scale is the holy grail for guitarists. It’s easy to play and it sounds amazing. This series will show you how to get the most out of our favourite scale, and how making small modifications will get you sounding like the pros and their signature sound.
A key ingredient to Clapton’s sound is blending the major and minor pentatonic. This can be most clearly heard the solo of Cream’s Robert Johnson cover “Crossroads”. The key notes we need to add are themajor 3rd and the 6th (see right), although I would recommend learning box 1 of the major pentatonic in its entirety.
“Crossroads” Lick examples
This lick starts with a hammer on from theminor 3rd to the major 3rd. Not only a quintessential Clapton move, but a very bluesy sound also. We also have a half bend between these two notes in bar 2.
This example utilises the 6th at fret 7 of the B string. This lick is almost split into major pentatonic in the first bar and then minor pentatonic in the second bar. Add vibrato to the C crotchet in bar 2 and pull off the semi quavers.
Clapton loves groups of three. This stye of lick can be heard in the guitar ad-libs at the end of “Bad Love”. Use hammer and pulls offs when playing the triplet on the B string
Clapton’s solo playing is full of string bending, both huge full tone bends and subtle smaller bends. With the full bends, I would always recommend having multiple fingers push the string (1st and 2nd behind the 3rd finger that bends the note). The half bend on the 5th fret of the G string can be achieved with just your 1st finger. Listen to“Cocaine” to hear this in action.

The slammed stop bar myth and movement in Tune-O-Matic bridges
by Terry Relph-Knight 27/02/18, copyright retained
This idea, that a screwed down stop tailpiece transfers vibration to the body and provides more sustain is an evil meme. It is perhaps something that some guitar journalist, who didn’t understand physics, wrote in some popular guitar magazine years ago and has been repeated mindlessly ever since.
For a start it is a contradiction – if the screwed down stop bar did provide a better mechanical coupling to the body then more of the string vibration would be adsorbed by the body resulting in LESS sustain. For sustain you want as much of your picking energy to remain in the string as long as possible. Bolting down the stop bar (and the bridge) reduces movement and lossy vibration in the components directly connected to the strings and that is why sustain may be affected.
Secondly the standard stop bar is not designed to be locked down. The design of the slots in the bar and the collars on the fixing bolts means that the stop bar is more or less equally coupled to the body no matter what height it is set at. To be able to couple the stop bar rigidly to the body you would need to use bolts without collars.
All the Gibson guitars that use a stop bar and an Advanced Bridge 1 or a ‘Nashville’ bridge (should probably be known as an ABR-2) derive from a guitar design using a trapeze tail piece. The stop bar, with its collared bolts, is actually designed to allow the string ends to be raised to approximately where they would be if a trapeze tailpiece was used, otherwise why would those bolts have collars?
If the stop bar is set as low to the body as it will go, over time there is so much pressure on the Tune-O-Matic bridges that they gradually start to collapse and bend in the middle.
Some guitarists recommend ‘top wrapping’ the strings, fitting the strings with the ball ends on the bridge side of the stop bar and then folding them back over the top of the bar. This method of installing the strings to the stop bar does allow the stop bar to be screwed down, while still providing a shallow break angle for the strings behind the bridge saddles. However, if the standard collared bolts are used, this method still does not lock the stop bar firmly to the body of the guitar and many people do not like the rough feel of the strings over the top of the stop bar, which over time will get scratched and grooved by the top wrapped strings.
So why top wrap, when you can use stop bar bolts without collars, fit spacers under the stop bar, and both lock the stop bar firmly in place and set it at the height it was always intended to be, which by the way reduces tuning problems by minimising string friction over the bridge saddles and doesn’t collapse the bridge.
If you are interested in this sort of stabilisation modification for your stop bar equipped guitar then please contact me via email@example.com or through an enquiry to the London Guitar Academy.
Slop in the Gibson style Tune-O-Matic ABR-1 and Nashville bridges
Like the standard Gibson style stop bar the Tune-O-Matic bridges rely on string tension for their mechanical stability and often have a degree of movement. The holes in the bridge have to be larger than the diameter of the support posts and the screw posts on the Nashville model are often not a tight fit in the threaded inserts into the top of the guitar.
Epiphone are to be applauded in their efforts in addressing this problem. Their solution, called ‘LockTone’, involves fitting small stainless steel leaf springs in the bridge holes and in the slots of the stop bar. This solution does not firmly lock the bridge or the stop bar in place, but even so Epiphone have published test results that they claim show improvements in sustain http://www.epiphone.com/News/Features/News/2011/Understanding-The-Epiphone-LockTone-Stopbar-Tune-o.aspx.
There are other solutions, from for example TonePros http://www.tonepros.com/ that will mechanically lock the bridge in place, improving sustain, tone and tuning stability.

Build Log: Bass Pedal Board build
Terry Relph-Knight copyright reserved.
This pedal board was commissioned to easily mimic the bass sounds of Roger Waters for a Pink Floyd tribute concert tour. The pedals used were already owned by the client. The intention of the board was to provide a durable, compact and portable effects package that could be easily set up at each performance. A prime requirement was that the client needed to have three basses plugged in to the pedal board, with each one easily selected by foot switch and that the pedal board provide a DI output, as well as an amplifier feed. Bass selection was accomplished using a Boss LS-2 Line Selector and a SansAmp Bass Driver Deluxe DI provided the DI and amplifier feed.
A Warwick Stage welded aluminium frame was chosen for the base, with power provided by a MEMTEQ Caline Power 5 switching power supply. Two of these supplies were purchased, one as a back-up. The pedals were attached to the base with mushroom stud Power Grip super velcro and Warwick flat Rockboard cables used for the pedal interconnects.
Warwick Step up wedges were fitted along the back of the Stage base, raising the SansAmp Bass Driver Deluxe DI, the delay, tremolo and EQ pedals for easy access to their foot switches.
Since the client was using his pedals almost continuously, the board layout had to be designed through a process of sending a series of emails back and forth, with final assembly completed in one day.
A couple of the pedals, the Korg Pitch Black tuner and the EHX Big Muff, had seen hard use and required some minor repairs.
Korg Pitch Black Tuner Tuner – mutes through path signal when activated
Boss OC-3 Super octave Frequency or pitch change – 1 octave and 2 octaves down
Has a polyphonic mode, dry/wet mix and can add distortion – 50mA
Big Muff Pi Fuzz type distortion (analogue)100mA
Nano Bass balls Filter – twin envelope filter (analogue)100mA
MXR cps 1974 Phase 90 Modulation – phase or notch filter (analogue) no LED – 2.2mA
Boss TR-2 Tremolo Modulation – amplitude (analogue)
TC Flashback Mini Delay Ambience – Delay (digital) 100mA has Toneprint BUT as far as I can see you can only program it with one Toneprint at a time and that sets the character of the pedal until you re-programme it. Some of the other TC pedals have a selector switch with positions for several Toneprints as well as various other modes. So if you load up an Echoplex Toneprint then the pedal acts like an Echoplex until re-programmed.
SansAmp Bass Driver Deluxe DI – 7mA
Boss LS-2 Line Selector / Looper – a two loop switching pedal. This can switch two loops in various selectable combinations – in parallel Loop A or Loop B or both, in series Loop A or Loop B or both. Or it can be used as an A or B to Y / Y to A or B switch. For example one input to two outs (to two amplifiers for example).
Behringer BEQ700 (its the boss copy)
Client needs to use three basses, to easily switch between them and may need to be able to drive two amplifiers. A DI output is also needed. This will be accomplished by using the BOSS LS-2 as a three way input selector and the SansAmp Bass Driver as a tone modifier with the effects in its FX loop and the two parallel outs and the DI out used for all the outputs.
Latest pedal layout scheme
Bass 1 into BOSS LS-2 FX return A, Bass 2 into BOSS LS-2 FX return B, Bass 3 into BOSS LS-2 input (via BEQ700 EQ pedal). With the mode selector set to A>B>Bypass, repeatedly clicking the foot switch on the LS-2 cycles through these inputs as indicated by a Green light for A, a Red light for B and no lights for Input/Bypass.
The output of the LS-2 feeds the Korg Pitch Black Tuner.
The output of the tuner goes to the input of the Tech21 SansAmp Bass Driver Deluxe DI.
The following effects go in this order into the FX loop of the SansAmp –
Boss OC-3 Super octave
Big Muff Pi Nano Bass balls MXR cps 1974 Phase 90 Boss TR-2 Tremolo TC Flashback Mini Delay (note – ‘One of these days’ may require Trem after Delay)
PedalTrain say that for 9 to 12 pedals a Novo 24 or a Classic 2 board should be big enough.
Looks like a Novo24 is the one, at £179 from Scan with flight case.

“One Of These Days”
Sounds like the delay with quite a bit of saturation, (so I may add the big muff for grunt)
The Phase 90 is on all the time I think..
So even though I will use the Phase 90 and the Big Muff separately on other tunes,
on ‘One Of These Days’ I will need to engage the Phase, Muff, and delay preferably in one switch
And then the TR-2 Tremolo, (at the end of the chain?) I can press separately for the second sound.
I Also need to keep the dry signal strong within the sound until I activate the tremolo which takes over the whole signal.
I may need a another bass overdrive Terry as well, maybe you could help me with this?
Just so once the big Muff is set for its roles, I can have a secondary drive pedal of a different kind
for other stuff. Actually the SansAmp bass driver does this stuff so maybe I need to dial in a preset for that… Yes, Mmm..
On other gigs I do I often use a Boss synth pedal ( believe it or not….!) and a second Octaver.
So I wonder will I just be able to interchange those pedals when I need to?
If it’s of any use, I have a an interesting pedal here too, Its the Boss LS-2 Line Selector.
It does loads of interesting things. It may be worth having a look if your not familiar.
It may help my cause I’m not sure.
I was hoping to use two amps on this gig if they will let me. I’m not 100 percent, but I think I could use the LS-2 to switch between amps according to the manual I downloaded.
I’d be happy to know what you think Terry.

Rolling Stones London Stadium 22nd May 2018
As a 25 year old, I was quite astounded when Sir Mick told me how he and the boys started “at the Marque Club in 1962”. That’s 56 years ago. My lifetime,doubled, and then some.
And it really was an evening of numbers. 6 decades of shows, 300 birthdays, 2 hours of hits, and 65000 fans, whose age gap was as large as the bands repertoire. They really are, in the words of Liam Gallagher (The Stones’ very well received support act), the ultimate rock ‘n’ roll stars.
Starting early, they jumped straight into “Street Fighting Man” and within seconds, everything seemed so familiar. Every movement, mannerism and sound from each individual synonymous with popular music history.
15 songs later, the show really built to a crescendo. The final sprint of “Start Me Up”, “Jumpin’ Jack Flash” and “Brown Sugar”, before an encore of “Gimme Shelter” and “(I Can’t Get No) Satisfaction” was live music at its very best.
As a guitarist, did I worry if the boys could still play? Of course. However, not only did Keith’s bluesy noodling soon put me at ease, but something else became clear. The sheer gravitas of the band I was lucky enough to be stood in front of would outweigh any technical difficulties these 70 year olds now face.
They had a great contingency plan too. Flanked with talented session musicians, led by Chuck Leavell (The Allman Brothers, Eric Clapton, George Harrison, David Gilmour, John Mayer), The Stones could relax and enjoy themselves, and it showed in their performance. Special mention to Sasha Alan who sang the legendary top line in “Gimme Shelter” perfectly.
One thing that needed no back up was Sir Mick Jagger’s showmanship. It was a full course of dancing, clapping, “YEH”-ing and hosting. The original and ultimate frontman.
With Gibson going bankrupt last week, and the absence of guitars in the charts, it’s easy to hop on the “guitar is dead” train. However last night fills me with confidence. At every turn you saw air guitars from young and old, teenage girls with Keith Richards lighting up their iPhone backgrounds, and Ronnie’s guitar solos awarded the loudest cheer. It may only be Rock ’n’ Roll, but a lot of people still like it.
