Hey, I've actually posted a problem similar to this one before and you guys were very helpful. Okay, so I have a Crate BT100 and a 1970 Fender Jazz Bass. My Crate stopped giving me sound today (during practice no less) and clearly it is an issue with a connection or something, not the fuse and not a short in the wiring or anything like that. It is also a problem with the amp, not the bass. Last time, I had a problem with the headphone jack. The connectors or whatever weren't making a connection, thus fooling the amp into thinking there were still headphones attached and giving me no sound. This time the fix I did last time isn't working, but when I plug in headphones, I do get sound. So my question is: are there any problems like the one I mentioned BESIDES headphone jack problems that would give me no sound, but still have the tuner, signal light, and headphone jack work? EDIT: I'm sorry for the misspelling of "Crate" in the title, I feel like an idiot haha.
