I think I have too many amps right now. I play Jazz or Rock, but I prefer a 'tubey' sound even for my jazz stuff. In addition to my practice amp, I have: Mesa M2000 - This amp is great for it's size and weight. Tons of power, and lots of options. Very punchy sound, but still warm. I can easily carry this and my basses in one trip. Still, all other things being equal I like the sound of an SVT better. SVT - II - Lots of headroom, pretty much any tone available. Since there is no seperate gain, can't dial up overdrive at low volumes, but besides that this thing is best of both worlds. The only problem - it's SO heavy, especially in it's flight case, and I rarely need all that power (most clubs in LA have good sounding PA's to send a DI to) V4BH - I just bought this because I thought it would a more convenient option than the SVT-II. It is lighter, but since it's so bulky I don't know if it really saves me that much schlepping. The sound however is fabulous, though it isn't as loud or as flexible as the SVT-II. Needless to say, all those amps are too many. Not to mention that my lady is eventually going to want some of that closet space back. I'm going to do some comparison testing both through the DI's and through a mic this weekend. Anyone out there have any thoughts?
