I’ve had this amp nearing two years now and it sounds pretty amazing. I know these aren’t the MIA Bad Cats, but for around home and recording demos it’s a sweet tone. Problem is recently it staters acting up. It powers, functions. When I play through it it still produces sound, but I get a lower sounding overtone that is not pleasant with every note, like a buzzing beneath what I play. I’ve swapped tubes (all 3) and played it through other cabinets and tried different guitars. Is this likely something simple or am I doomed to bring it to a tech?

Thanks for any input.

I experienced the same problem with an amplifier I had. How old are the power tubes. Have you changed them recently? It worked for me. It can't hurt while you wait for the amp techs to show up here.
