Own an ibanez sr506. Works beautifully. Brought it too a friends house today, plugged it in, it was really quiet. Compaired it with his bass, his bass was louder. Swapped cables, seemed to fix it. I get home, plug in my bass to my cab, and all I'm getting is a faint whisper of bass. So I swapped out the battery for a new one and switched cables, nothing. Same thing. I opened up the control cavity, everything was in perfect order. What gives!?!?
