Wow! just got back from playing a festival. Usually I'd bring my 2x10, but thought why lug it. I know the sound guys and figured small amp would be plenty. I've been liking the way the Pro Jr turned out and it was a pleasure roaring through it today~and the guys also thought it sounded great Harp went through Masco and 4x8 cab, backline bass amp was an SVT, and drums were fully miced. Set my vol on 6 1/2 tone 4 1/2. Guess good sound sound guys and a little amp is all you need!
