Annoying Ampeg BA115 buzzing.

Discussion in 'Amps and Cabs [BG]' started by RandomBox, Jan 28, 2014.

  1. I bought this amp last month to replace my old 25 watt, and it played smoothly until this week. Now whenever I strum certain low or high notes, the amp has a small buzzing sound. I wasn't concerned at first, but now it's getting annoying.

    I know it's not my bass, because I've tried 3 basses with the same result.

    I've zeroed the sound in to the small box attached to the amp next to the power cord output. And the buzzing changes pitch occasionally. Other high notes and mids sound fine, but E string and certain A string notes make it buzz.

    Anyone have this issue before, or know how to fix it?

    Transformer enclosure. Needs to be tightened down. You may have to do it from inside the amp chassis. Be careful.
  3. I'll see what I can do. Although it seems the enclosure is tight, the buzzing seems to be from the inside of it.
  4. Yeah, sounds like something is loose in there.
