Hello, 1st post here! I bought a Celebrity bass. The pickup works untill you switch the preamp ON, then it just goes dead. Could someone tell me how to troubleshoot this? It's a beater guitar that I only payed $50 for, so I would like to try and fix it myself. Anyone know where I could find a schematic for this preamp? Is it even worth trying to fix, or should I be looking to upgrade it? Thanks in advance, Casey

First, Welcome Casey! :cool:

Second, which button are you pushing to switch it ON?



And you say that it "Works until you switch the preamp ON"?
(so I guess you are really switching it OFF, huh?)

And there are smarter people here than me... They will be along shortly. :D

The top button is the preamp in/out switch. Silly question... did you try a new battery?

Yes, the top button. Good battery. When I switch it to "in" the thing goes dead. I have pulled it out of the guitar and pulled the preamp covers off, but I can't find out how to trouble-shoot it. None of the components are visibly damaged or burned, but I know electronics can be tricky. Any ideas would be greatly appreciated. Thanks for the suggestions so far!
