You don't happen to be at the Bedrock Studios complex, do you? Anyway, we used to practice there, and there is serious AM radio interference due to some tower in the very near vicinity. My friend's Mesa head would pick that shit up real well.

Bumping this because I just moved to a new practice spot, closer to downtown Louisville than our last place, and my Orange OR120 is now picking up radio interference. It has never done this in the past, anywhere. I tried moving it around the room, rotating it at different angles, I tried different power outlets, surge protectors, two different power conditioners, I took pedals out of my chain one by one, then took the whole board out of the signal path, I tried different instrument cables. It was still getting it with nothing plugged in, so I tried a different speaker cable. Still there. I tried swapping preamp tubes. Still there. In fact, the problem only stopped when I took the preamp tube out of the V1 slot. So, I have a tech friend checking it out now. I haven't even tested the rest of the amps aside from a Peavey Classic 50, which doesn't pick up the RFI. Frustrating.
