Can you describe the hum? Is it 60hz hum like thru a single coil, or does it sound more like a buzz? Does it change when you move around/face a different direction and/or does it change if you move the pedal around?
I had a bad hum coming from another preamp pedal, turns out it was the National Guard. Drove me crazy for awhile![]()
It was the instrument cable I was using going out of my compressor pedal to my audio source. I have a 90 degree input jack with a silent plug, with a normal straight jack on the other end.
I recently picked up a Dingwall and only a straight jack will work so I just reversed the two ends.
