tone pot issues
replaced the tone pot on my Peavey foundation today and am still getting 0 response out of it. Wired it the same and as it was.
W + R on center prong.
Bare wire to the base
copasitor to the left prong and base.
took a pic before removing everything to insure it went in the same way it came out.
Help guys please? :help:
1.) It depends on which Peavey you have.
The old 1970s/80s sometimes had very special pots for tone+coil split ...
2.) But your description sounds like a normal tone pot ...
The pot has nothing to do with tone or volume. These are (often) the same and are only for the regulation. The capacitor is the important thing to turn a pot into a tone pot ...
So, I would say the capacitor is broken. If it had a short cup, the pot would work like a volume. If it is broken (no connection inside), it doesn't work at all.
You should get a new capacitor (22nF to 68nF is normal) for some Cents ...
A standard capacitor has 47nF / 50nF which is also called .05µF ...
switched the capasitor with one I got from a scrapped Pbass and still got nothing. Might hit radio shack in a bit and try a new compasitor to insure I didn't switch 1 broken piece for another. The pot I put in was new though.
Can you make a photo of the wiring?
pics would really help here, this is a fairly simple diagram so send us a pic or two and maybe we can help more...
You may have damaged the pot by over heating it when soldering, especially when soldering to the back of the pot.
I'll try and get pics later. Can't right now.
The soldering iron is only 30w.
From your first post, we still don't know what "W + R" really means ...
Theoretically these could come from PUs and go to volume pot (which was right).
But we don't know ...
And as I wrote ...
Some old Peaveys have a special wiring with special pots!
We event don't know which Peavey bass. A T-40 is totally different to a 2012 passive Peavey bass ...
The capasitor wasn't properly grounded to the base of the pot so i resoldered it and it works fine now.
and to clear things up,
Its an 84' foundation.
W = white wire
R = red wire
Thanks for the help guys. truly appreciate it.
