Re: Trying to fix up my 59 for jazz
I've been curiously following along and can't wrap my head around what you want out of the tone control. Part of it is because I'm more like Lew in that I'd rather not knock down the treble of most HBs in the neck. Even with the bridge, I've gone so far as to stick something like a 22k in series so the tone control never reaches that place were tone takes that insane nose-dive.
Anyway, if you want 1-3 then just put a series R with the value you get when the pot is on 1. Measure the pot at 3 and subtract the series R and that's what you want for your pot value on full which you can achieve by picking a pot with the closest value but higher and fine tune with a parallel resistor, also paying attention to how you want it to taper. You probably know this already, but for anyone else who's curious...
A push/pull can be good to disengage the effect (and you might want a bigger pot if you want it to switch to a more traditional tone control). No load mod can be cool too, but I know you like using dual-gangs and don't know how easy it can be done with those (or with pots that are combined with switches). If you or anyone else has successfully modded these types of pots, I'd love to hear about the gory details.
