Fender Standard Stratocaster
v.2.0
Since I wrote up the original
entry on this guitar, I performed a complete overhaul on it, turning
it into a close approximation of Eric Clapton's famous "Blackie." The original
Blackie was on the cover of a several EC albums including Timepieces.
In reality, that guitar was retired long ago.
In the last decade or so, Clapton began
using a new Strat with Gold Lace Sensor pickups. Eventually, a signature
model was commissioned and modeled after the original Blackie, but with
all the electronics of the modern era. I wanted to get the look a
little closer to said signature model, I would have had to replace the
tuners, and I'm in no rush to do that. |
Modification
#1: Gold Lace sensor pickups
These have a really classic sound
yet give off no 60 Hz hum like most single coil pickups. I highly
recommend these pickups in any Strat.
Modification
#2: High-pass capacitor
Control: n/a
Function: Placing a very low value
capacitor (.001 microfarad) across the appropriate lugs of your volume
knob (or knobs) will keep your tone from loosing the high frequencies (i.e.
getting "muddy").
Modification
#3: Phase switch on middle pickup
Control: Push-pull pot
under the middle (tone) knob.
Function: Throws the middle pickup
electrically out of phase with whatever other pickup it is combined.
Modification
#4: TBX
tone control
Control: Middle (tone)
knob.
Function: This is an unusual passive
(no batteries required) tone control that will cut either the treble or
bass frequencies depending which way you turn it (middle position equals
bypass). The standard tone control only cuts treble. It gives
you an extra degree of brightness. I have this set up as the master
tone knob; the other tone knob was commandeered for mod #6 below.
Modification
#5: (Selectable*) parallel wiring combinations
Control: Push-pull pot
under the volume knob
Function: This is a switch that
selects the bridge or neck pickup to combinations when it isn't otherwise
selected. This allows you to have all three pickups on at the same
time or the bridge and neck, which sounds like a Telecaster.
| 5-way output with the Parallel selected: |
-
Neck (+ Bridge)
-
Neck + Mid (+ Bridge)
-
Mid
-
(Neck +) Mid + Bridge
-
(Neck +) Bridge
|
*I say "selectable" because this
is done with a switch rather than a potentiometer... as opposed to the
alternative below....
Modification
#6: (Graded*) series wiring combinations
Control: Push-pull pot
under the middle (tone) knob.
Function: This is accomplished though
a potentiometer instead of a switch. Normally all combinations of
pickups in a Strat are in parallel. However, series combinations
give an altogether different sound, much more like a Les Paul. In
this case, this option allows the middle pickup to be combined in series
with either of the other two.
| 5-way output with the Series fully selected: |
-
Neck + Mid in series
-
Mid
-
Mid
-
Mid
-
Bridge + Mid in series
|
*I say "graded" because this is
"dialed-in" with the potentiometer. You can do this mod with a switch
as well, but then it's all-or-nothing.
(future)
Modification:
Clapton on-board pre-amp*
Control: Who knows?
Something's going to have to give; I'm out of knobs!
Function: This is a mid-range boost
featured in the Clapton signature Strat and represents the only thing separating
this guitar from his (in terms of the electronics). This boost gives
that thick tone that is superhuman or (dare I say it?) God-like.
*Available at Guitar
Electronics. If anyone has tried this model, let me know what
you think of it.
| The Big
Picture
The basic "stock" Strat only allows only
5 combinations of pickups. .
| Stock |
-
Neck
-
Neck + Mid
-
Mid
-
Mid + Bridge
-
Bridge
|
The configuration in this guitar allows 12
more
combinations in addition to the five above:
| with the series blender on: |
-
Neck + Mid in series
-
Bridge + Mid in series
|
| and... with the parallel blender on: |
-
Neck + Bridge
-
Neck + Mid + Bridge
|
| and... with the series blender & parallel
blender on: |
-
Neck + Bridge in parallel combined with Mid
in series
|
| and... with the phase on: |
-
Neck + Mid out of phase
-
Mid + Bridge out of phase
|
| and... with the series blender & phase
on: |
-
Neck + Mid in series out of phase
-
Bridge + Mid in series out of phase
|
| and... with the parallel blender &
phase on: |
-
Neck + Bridge
-
Neck + Mid + Bridge
|
| and... with series blender & parallel
blender on: |
-
Neck + Bridge in parallel combined with Mid
in series and out of phase (whew!)

Ideas on this
page for the series and parallel blender/switch were based on a design
by the Electron
Times.
The schematic
Depending on the manufacturer,
different 5-way switches have different configurations of contacts.
This diagram doesn't specify which way is "up" or which direction is forward
(i.e., position #1 vs. position #5, not that anyone is ever consistent
in using these designations anyway). When you prepare to assemble
your own circuit, use a multi-meter to test the continutity between the
common of each pole and the other lugs so you can determine which position
selects the neck pickup, etc.
In this diagram, the gray wires
go to ground... except where the ground symbols from the neck and bridge
pickups combine in parallel, then eventually meet up with the middle pickup
ground from the phase switch (assuming the phase has not been reversed,
that is). Other colors were chosen arbitrarily. Different pickups
will have different color codes for the wires. If you wish to add
a 4-conductor humbucker, consult the manufacturer's website for which wires
feed from which coils.
The cap (orange circle) associated with
the TBX is 0.02 µF and the fixed resistor (orange rectangle) is 82k
Ohms.
This schematic covers all the mods listed
on this page except for the EC pre-amp which was installed later.
