First post, sorry if I'm trolling. Anyway, I have a problem with my Yamaha RBX374. It's my first bass guitar, and I just got it in mid May. Problem is, around late-late June, the guitar was making funny noises from the amp, then the next day it went completely dead. I went to Guitar Center to get it fixed, and figured that my bass's 9V battery for the active electronics was dead. So I replaced it and it worked fine... but after less than 2 weeks, the battery died again. So my question is, is the bass guitar supposed to burn through 9V batteries this fast, or is it part of using active electronics?
