I wanted to try the mod with adding a cheap piezo that was discussed in another post, problem is I can't get it to work properly. I've installed the piezo in my P-bass and I want to control it with a separate volume pot and also be able to control it with the tone pot. So I'll have two volume pots and one tone. I've resoldered it about 6 different ways now and I can't get it right. Ant ideas? Please? Would it be easier to just wire the piezo with the volume pot and only use the tone for the P-bass PUP?
