When I got too old to lug my ac30 about at two in the morning I changed to an Ac15. What a great amp. Several soundmen ( including the boys who had just come back from liveaid)told me at gigs when they miked it up that it was the best sound ever. It didn't matter where you set the controls, it sounded terrific.
Still got it tucked away unused for probably 10 years now........
