Hi guys, This hust happened one morning out of the blue. I'm having a bit of trouble with the onboard in my FBass and was wondering if it might be a quick fix. It seems the pull/push bridge volume does not work in humbucker mode (knob "out" position). It works fine in single coil. I tried moving some wires around, hoping it was a short between a wire and the circuit board and even put some foam between the wires and the board but nah...that wasn't it. Any suggestions before I take it in?
