I play mostly blues,classic rock, a few heavier songs in the set Dokken/Slash type stuff. I run my amps clean and punchy, meaning more power tube distortion tone than preamp. Usually the preamp volume is around 12 - 2 o'clock. I have a few different pedals to kick in a little more drive. It's never been an issue until I put in the BB2. Now when I step on a pedal..squeal. It's ok while I have my volume on my guitar rolled back to 8 or so and below. Wide open...squeal. I'm used to using volume and tone controls all the time while playing so not a problem...just hate the squeal!!! The other Les Paul with BB would get singing feedback, never squeal. Couldn't make it squeal.
