Well, I did 2 gigs this past weekend with the Ampeg SVT 7 Pro. I'll say this, I like the amp a lot! In 2 seconds I had a sound I was very happy with. If you like the Ampeg sound, this amplifier doesn't disappoint. The gain can be turned up to get nice bit of "crunch". Even more gain gets you fuzz bass heaven! Back the gain down and this baby is clean and loud. This is the first class D bass amplifier where I was able to get the sound I wanted and the power to go along with it. The class D is buttery smooth and feels more like an all tube amp than a hybrid to me. There are getting to be more "lightweight" amps out there, but before buy anything I'd suggest you test drive the SVT 7 Pro. I tried 4 other class D babies, and this is the one that sounds the best to me.
