Before I sprung for a valve head, I borrowed one off a very kind friend for a practice session, hand-built 100w, through my Barefaced Four10 at the practice, I couldn't even hear it at full beans, swapped back to my Orange Terror 500 after 3 songs. Admittedly we played silly loud at that time, so I went for a Matamp GT200 after that experience, no problem hearing that, indeed Kev (r.i.p) was even moved to say, "Ffs turn that thing down" at one session when i decided to give him some of his own medicine.
Loud is different things to different people.
