Hey all! I have a no-name jazz bass and years ago my dad changed a pot from it. I can't remember which one. Despite all the wiring schemes he couldn't get a sound out of it. Then an engineer tried to fix it. Now the volumes work, but the tone pot acts sort of master volume, except when it's totally off it doesn't cut the sound off completely. It doesn't bother me much, but I would like to know what is wrong. I tried comparing the wiring with pictures and can't see anything wrong. Mind you, I don't know anything about these things. Any ideas?
