Ive been playing my bass (Ibanez sr300fm) for about a year and a half and for the past few months after about 15 minutes of playing it it becomes really distorted, especially on the lower notes and bassier sounds. I know it's not the amp or cable, because I've tried it on several amps and with several cables.

I've had suggestions that the pickups might be dirty or something but i dunno, have you guys got any suggestions on what it might be or what I could do to fix it?

Sounds like a dead battery to me.
