    At rehearsal today, my Ampeg would go from quiet to loud over and over while I played. I changed chords and batteries but nothing worked. Anybody know what is wrong?

    happened to my hartke a long itme ago...ended up being a whole slew of loose connections inside. My father fixed it since he works with electronics for a living, but it should be cheap to get fixed at a local electronics shop.
  3. Did you change "chords" (like from Dm7 to Gsus4)?, or "cords", like an instrument cable?

    Just kidding you, that's weird, and since I own the same amp, let me know what you find out. Could it be the jack on your bass guitar?

    Yes cords not "chords." I don't think it's the bass because this doesn't happen with my other amps. Must be something inside of the amp. It's weird because the sound gets quiet then very loud then quiet again.

    Is there some kind of thermal protection going on? A lot of power amps will go into reduced power mode if it starts to overheat.
