Carvin Amp Serial Number Lookup
Most Amps will buzz or hum when there is a bad ground. It could be because you're plugged into an outlet with some other piece of equipment on it like a motor. If it buzzes on every outlet then there's probably a ground issue in the amp. You can try cleaning your 1/4 jacks with cleaner cause sometimes they'll get cruddy and make for a bad connection. I wouldn't recommend opening the amp and messing around with anything since you could zap yourself. If the amp buzzes withouth even having anything plugged in, then yeah, it's probably the amp with the bad ground. If it buzzes with instrument plugged in, then maybe it's a plug on your instrument since they have to deal with movement and can go faulty after a while.

If the amp is still under warranty, take it in to be serviced.
