When my amp is on and i walk around in my room, the tubes rattle from the slightest movment of anything around it. even if i drop a quarter on the amp the tubes rattle for quite some time.
How long have you had them valves in the amp?
The amp is a good 4 or 5 years old. and everytime i play a gig or something i blast the thing on 12 and overdrive the **** out of it so i can get feedback for jimi hendrix type playing.
maybe the reverb tank is vibrating, if you have one
even if it's not the tubes, you should get some new ones probably, if you haven't changed them in that whole time.
Yeah i havent really changed them. Ive played through a few other amps in those years but this amp is the oldest. i want to get tubes with a little more power and bass range. the amp is quite trebly and has a lot of high end. Now i think it has 4 12ax7s and 2 el84s i think? any recomendations.
