Electronics. I used a 4-pole mag pup and double piezos. The volume pot is a B100k and the tone pot is a A500k with .047 orange drop cap, all wired through a three-way Strat-style switch. The combinations of tone are unbelievable!

Hey Kid, thanks, no heat sink here. The cap is big like a fire cracker with very long leads. I don't think i'm overheating the beast, but maybe i am. I've never used the heat sink idea. Don't know how yet. Better learn eh?...
Hey Dave if your tone pots are repeatedly not working for you have you considered you might be frying the caps when you solder?
There's lots of ways to wire a treble bleed type tone pot which look different but all work pretty much the same. Do you have a heat sink for your capacitors mate?
Dave, if my strings are grounded it's by osmosis :). My pup is 1/2 of a pair of Gitty's 4 pole pups: https://www.cbgitty.com/cubecart/pair-of-black-enclosed-4-pole-pick.... I wouldn't mix wiring diagrams. Try a A500k on the tone as well. I switched to the linear volume pot 'cause the signal cut out completely around "7". Now I get almost a full sweep.
Hal, are your strings grounded to that central ground? I've use 250pots as mine is a single coil pup. I've crossed my big capacitor from the tone pot to the volume pot (a lot of old lap steels did this). I've got a couple of wiring diagrams that i'm following. They conflict however. I'll try the other one when i break my beast back down. One more time might be the magic cure...? Is your pup a humbucker? I used a .047 cap... I've never tried a B100k pot... gotta try one i guess... Thanks, Dave
Dave, all the black wires are converged into one ground (notice the marker-colored wire from the pup). Hope that helps. I always had problems with tone pots, too - this is the first one I've been happy with. What size caps and pots are you using? I did have an audio taper A500k volume pot on this at first and didn't like it. Found the B100k linear pot in my parts bin, threw that in and the whole setup came alive. I lucked out. I don't pretend to know anything about electronics. It's all majic to me. I think if I did the exact same setup on another git it would sound different.
Well it's clear to me except where your wires merge in the harness in the middle. I can see the tone and volume pots clearly though and that's where i need the work. My tone pots don't do it right yet. I've not had them working right so far in several attempts. They just don't do anything to the tone. Where does that black ground wire go from the back of the tone pot into the harness? Thanks for the link too. Much appreciated Hal ... Dave
LOL - clear as mud, right? I wired everything up to test before I mounted or drilled anything in the box, that's why some of those wires are so long. I used the diagram here: http://www.artecsound.com/wiring/wiring_book01.pdf Scroll down to page 11. I just substituted the double parallel-wired piezos for the bridge pickup. Works like a charm.

Thanks for the comments!
Thanks for the clear wiring photo. I need this...
