New here, not sure where to post or even if I can find answers. I have Crate BT220 bass combo, worked beautiful til I went to pick it up from where it was. Took it to rehearsal, and the sound started getting real low, the limiting ligt started coming on, and heard a 60 hz hum starting, which the volume control did not affect. Now, there is barely any sound coming out except for the 60 hz hum, doesnt matter where the volume settings are set to, same sound. And ideas?
