I heard replacing tubes or something in a tube amp could make it sound alot better? so if i were to put a new set of different tubes into my vyper 60 it would make it sound better then it does already?
not really. Other amps more so thenthe vyper 60. There's not enough tube interaction for a tube swap to make a significant different.
Isn't that the one running two 6L6s? I doubt you'd notice a lot of difference unless they are beginning to fail. What brand of valve is in it now out of interest?
