Used my Black Face Walkabout 15 Scout on 5 Gigs and my guitarists love the sound, One guitarist uses a Mesa F 50 2 x 12 combo , 5 piece drum kit , and other guitarist uses Fender 4 x 10 and its plenty loud enough.
I have all knobs at 12 O'Clock except Pre Amp is 1 ish and I play with Low para to offset rumble.
They have a great pre amp and a very inspiring sound to me.
BUY ONE !!!!!!!!! you will not regret it
