The Eldred Esquire wiring schematic. Illustration
courtesy of www.singlecoil.comThis month, let’s continue exploring
Esquire mods by diving into the socalled
“Eldred Esquire wiring,” which is
currently one of the most popular wiring
schemes for this iconic Fender model. The
Eldred wiring is named after Mike Eldred,
who directs the Fender Custom Shop. (This
must be one of the dream jobs in today’s
guitar industry!) Mike came up with this
wiring for his personal Esquire and it was
an instant success.
In addition to managing the Custom
Shop, Mike is also a great guitarist who
gigs a lot with his trio, so he knows what a
guitarist really needs. I had the pleasure of
meeting Mike at one of the winter NAMM
shows in California, and he’s a very nice and
funny guy, too. (Visit fendercustomshop.com
and mikeeldredtrio.com for a closer look at
Mike’s work.)
Like so many other Esquire players,
Mike doesn’t like the stock switching position
#3, which routes the guitar’s single
pickup through the volume control and
a fixed “treble roll-off ” capacitor/resistor
network. Here is the switching matrix of
his preferred system:
• Switching position #1. This rear
position is the same as on a standard
Esquire. The pickup is routed through
the volume control only, with the tone
control bypassed for a hotter, louder
lead sound with extra highs.
• Switching position #2. This middle
position is also the same as on a standard
Esquire, with the pickup routed
through the volume and tone controls.
It sounds a little warmer than
position #1.
• Switching position #3. In the front
position of the Eldred Esquire wiring,
the pickup is routed through a single,
small capacitor and volume control,
with the tone control bypassed once
again. You might think this is a very
small and lame modification because it
consists of nothing more than removing
the fixed treble roll-off network
and replacing it with a capacitor. But
it’s a very effective mod that’s both versatile
and useful.
Adding the small capacitor and entirely
removing the treble roll-off network gives
this switching position a kind of “oh-oh”
vocal quality and creates a scooped and hollow
midrange that sounds nice and warm.
This specific sound is also called the “cocked
wah tone.” When playing an Esquire that’s
wired this way, anyone with a wah pedal will
immediately know why. Using some volume
swells (the volume pot is still engaged in
this switching position), you can completely
mimic a wah pedal, once—like the great
Greg Koch or Jim Campilongo—you master
the playing technique.
To hear how this switching works and
sounds, you can watch a video from the
Fender Custom Shop, where Mike walks you
through his switching system on a relic’d ’50s
top-bound Esquire (YouTube search term:
LTD Release ‘50s Top Bound Esquire Relic).
So what do you need to set up this
switching? Not very much—just an additional
4700 pF (0.0047 μF) capacitor and
some wire. That’s it. The project basically
involves removing the treble roll-off
network, throwing in the new capacitor,
and moving some wires. Generally, this
wiring sounds best with two 250k pots
and a traditional Esquire/Telecaster bridge
pickup. Mike actually prefers a hotter
bridge pickup model with a more prominent
midrange. Fig. 1 shows the Eldred
Esquire wiring schematic.
Even though the Eldred wiring is versatile
and sounds great, it’s no crime to
customize it to your personal preference.
Here are some ways to experiment with
this wiring:
• Start with the 0.047 μF tonecap
from the standard Esquire circuit and
then experiment with the value and
the type of the cap. In several earlier
columns, I’ve discussed the various
options in detail.
• Mike prefers a standard film/foil 4700
pF cap for switching position #3. You
can experiment with the value of this
cap to dial in the tone you want. A
lower value than 4700 pF will result
in more highs because less treble is
bled to ground and vice versa. A good
range to tinker with is 1000 pF up to
6800 pF, but naturally you can use
any value you like.
• Another excellent area to experiment
with is the type of cap you choose to
replace the stock treble roll-off network.
You can try ceramic, film/foil,
paper-in-oil, paper waxed, silver mica,
Styroflex, or anything you would
like to try. Personally I prefer a 715P
or 225P Orange Drop cap for this,
because these caps also offer a prominent
midrange scoop that perfectly
supports the vocal “oh” quality of the
tone. These caps really fit like a pair of
old shoes with this wiring. But it can
also be interesting to use a completely
different cap (and value), making the
“oh” sound more like an “uh” or “ah.”
I think you know what I mean!
In next month’s column, I’ll share my
personal custom version of the Eldred
wiring and explain how the Esquire I use
onstage is configured, so stay tuned. Until
then, keep on modding!
