Re: Is the Jerry Donahue wiring scheme truly a mystery to the public?
Very cool thread. I just bought a Tele, and I'm looking into what mods I want to do. Series/parallel is a must, and the halfway out of phase looks really cool. Otherwise, which aspects of the Jerry Donahue Tele/Omniac/etc do y'all use the most? The sparkle-tone mod mentioned here and with its own thread also looks interesting - seems to be just the opposite of a couple of the JD settings where some of the neck's highs are shunted to ground. With the sparkle-tone, you borrow some highs from the bridge pickup. I'm thinking of doing essentially ArtieToo's JD Telecaster-alt schematic, and maybe add a on/off/on toggle to add a 0.0022 and 0.0033 uF caps to the neck's hot lead, as well as a push/pull pot at the volume to make the sparkle-mod switchable. Anybody have any experience with mixing these mods? I'd hate to put a lot of work into making 2 things that just cancel each other out, or are just incompatible. OK, it's not really THAT much work, but that tiny cavity is getting pretty crowded. Very crude drawing below. It's close enough to the "modern" tele wiring that you'd want a treble beed RC, right? Or is there a way that this could be wired up 50s style to remove the need for the treble bleed?
Thanks,
Michael

SIDENOTE - If your pickups are RWRP to cancel hum, the HOOP wiring will defeat this ability.
And I personally prefer to use a smaller cap for HOOP: 4,7n instead of 10n. sounds more Strat like to me. YMMV.
FWIW...

Sup guys, first time posting here, but long time stalker.
Have you seen his Vintage signature guitar? Wiring seems to be a little different, since Pos 1 and 2 use only the neck PUP. As per Premier Guitar:
"Position 1 engages a Wilkinson WJTDn Alnico II single-coil, which, interestingly, is intended to provide the sound of a ’60s/’70s Stratocaster neck pickup. It’s certainly in the ballpark, and by any standard sounds quite good—with the requisite spank and a pleasing balance of warm roundness and sparkly highs. It fared best with clean and moderately overdriven amp settings.
Position 2 gets you the same pickup, but adds extra capacitance to the circuit with the aim of emulating both fatback jazz guitars and Eric Clapton’s late-’60s Cream tones. A Gibson L-5 or ES-335 it is not, but the lack-of-woodiness factor notwithstanding, the tone is surprisingly humbucker-like and sounded good on all amp settings from clean to high-gain"
I'm curious about this wiring, cause a friend of mine has an Esquire and we're studying some possibilities
Cheers

Re: Is the Jerry Donahue wiring scheme truly a mystery to the public?
"Position 2" apparently puts a cap in parallel with the pickup. It's an old recipe, recommended for ages by Bill Lawrence and that I've applied myself dozens of times.
The trick is simply to use a capacitor of small value, measuring more than 1nF (=0.001µ) and less than 10nF (= 0.01µ). 2.2nF is a good value to start with. It enhances the mids and reduces the high range by shifting down the "resonant frequency" in the hi mids. If the sounds becomes too nasal, just add a resistor in parallel with the cap, in order to obtain a rounder resonant peak (and the related rounder tone)...
