If your guitar amplifier suddenly has stopped producing volume or any output whatsoever, there are a few standard procedures you should check.
- If it’s a tube amp, have you checked the tubes? Both preamp and power amp? If you play your amp weekly, then you should get at least a year out of your tubes, but if you play every day with a tube amp, they might fail more quickly.
- Is the speaker blown? This is less likely unless you play your amp extremely loud quite often.
- Are all internal cables connected if it’s a combo amp? You’d be surprised at how often this is the case.
- Have you checked all your cables properly? Are you sure it’s not the guitar?
Once you’ve eliminated some common sense starting points, it’s time to either take your amp in for repair to a reputable amp shop. If you don’t know one, ask some local players to make recommendations, since amp techs are not as common as guitar techs.
