It was making a funny noise

    I had a contest tonight and during the first song (which was a big band swing song), my amp started to go up in volume and down again slowly. Sorta like a wah-pedal would do. It only happened during that song though. We played a latin and ballad song after that and it didn't do it. Does anyone know why this happened. If you do, can you help me out. :help:

    Just a thought... Are you sure it was your amp?

    My guitarist brought this tremelo pedal to rehearsal, and didn't mention it one night... He started using it during this slow groovy Roy Orbisonesque tune we do, and his frequencies were kind of meshing with mine. I thought my amp volume was modulating and my amp was about to be toast... A few seconds later though, he moved to a higher register and I could hear what was going on.

    Or you might need to take the amp to a good tech and get it checked out. :D

    Cheers,
    Chris

    I used to play through an Ampeg B2R. One gig, during sound check, it started doing the same thing. Turned out the power to the stage was crud and when I really reached for some emphasis, the volume dropped and then would rise. A dedicated power cord to a seperate circuit solved the problem. My next purchase was a power conditioner with voltage regulation. Hope this helps, though it may not be the same problem.

    What kind of amp is it? Has the problem resurfaced?
