I recently purchased a thunderbird and it sounded great in the studio (i think they were using this ampeg head) And I was wondering why the sound sucks when I practice at home, since i'm a novice in amps, I looked up mine and it has only 10w (Epiphone studio bass 10), I've been eyeing a fender rumble 75 but would it be too loud? or a 30w amp would be better? any advice?
