I was playing through the amp this morning at low bedroom volumes (1-2) and my amp started to buzz LOUD enough to shake my entire house. No guitar sounds can be heard during this buzz. I had to turn the amp off right away. After I disconnected my guitar pedals and plugged straight in it worked fine again. This has happened about three other times within the last two months but only when I'm using the following scenario. 1. Pedals are plugged into the same outlet as the amplifier. 2. Using telecaster with maybe bad grounding? I installed new pickups myself on it. When I plug my pedals into a different outlet in the room it seems to fix the problem? I don't know if this is the real issue though as I've been plugging the pedals and amp into the same outlet for about 3 years now. I never played the telecaster much before this started happening. I'm currently playing into it with my jazz master and no pedals and it's working just fine.... It almost sounds like it's an internal problem with the amp but it is puzzling me why it is random... Anyone have this issue before? I would like to prevent this from happening again because it scares the sh*t out of everyone that I live with.
