New Schecter Bass Has Low Output?

Check the battery, I think the Customs are active, and a low battery will mean screwy signals.

 

It could be the pre-amp is bad.. if so you'd want to return the bass and get another. I don't think Schecter electronics are very good at all.

You'd have to take it to a repair shop to see for sure if the preamp is bad. If you know anything about electronics and wiring you could bypass the preamp internally and set the pickups to go straight to the output jack. If that gives you powerful sound, that would mean the preamp is busted.

 

could just be you need to adjust your gain on your amp for that particular bass...did it have a low output at the store? some active basses have lower outputs than passive basses....I had a Fender deluxe jazz that had an output of about half what my passive P bass was. I just had to compensate by increasing the gain on the jazz or use my line mixer to accomodate the differences in outputs of whatever 2 basses I may be using at the time.
