My friend brought over a bass he wanted me to look at for another one of his friends. It's a Rogue XB Pro 4. (i just looked it up) So at first, we couldn't get any sound out of it save for a few crackles, but then I looked in the battery box and there was nothing in there. I borrowed the battery out of my EBow and gave the bass some life, but then the signal coming out of the bass seemed to be totally distorted. It sounded as if there was a fuzzbox built into the thing, but none of the knobs really cut back the distortion. Does anyone know what's going on here?
