Right, just got my 2nd rumble 100, first one didn't work, just a faint noise at full volume and the new one is just the same.
I have to have the o/d switched in to get any volume at all. Just gain and volume produce very little at all, is it meant to have the overdrive on constantly to get any volume? what am I missing here? The drive and level knobs seem to control all the volume. I don't want overdrive.
help!
