Hi, I'm a starting out beginner and I was wondering if my feedback on my overdrive channel is normal. When I play with the pickup tone knob all the way down there is no buzz what so ever, but when I play with the tone knob up I get a very loud buzzing feedback. I think my overdrive sounds better with the tone all the way up.....but this feedback kills me. Also if it helps my bass has only 1 soap bar humbucker pickup. Thanks!
