For the past few months, Ive been rehearsing and gigging with a Mesa/Boogie Bass 400 (KT-88's) and a Goliath III 4x10/Mesa Powerhouse 4x10 cabinet setup. When I was using 6L6 tubes, even at pretty high volumes, the cabinets were being pushed pretty minimally, and sounded great mixed. However, now that I have a lot more power with this head I am finding that at gig volume, the Goliath III is getting pushed to the point where you start noticing its lack of heavy low end. I was plugged into just my Mesa cabinet this afternoon and fell in love with the tone all over again. Since the G-III is a lot more efficient than the Powerhouse, that tends to be what you hear more, but the Mesa tone is what I really like. I still like this setup, but am starting to consider two alternatives- Trade/sell off G-III, pick up another Mesa cabinet. Sell off G-III and other cabs I have, pick up one of the larger Schroeder cabinets as a standalone. Supposedly Schroeders make all your dreams come true.
