California Blondes are awesome amps. I usually play mine through that. Give you a wide range of knobs to help find your specific sound. Bass amps are pretty cool also, I used to play through an old Fender Bass amp, just a real deep clean sound, add that in with a chorus pedal, and maybe a little envelope filter, and its a heavenly sound. 
I once heard Dave Matthews started on a bass amp, I mean during his early times, does not matter too much I suppose. Considering now he plays through an entire wall of effects and mikes his guitar and mixes it with an amp and also, directly into the mains. 
Oh well.
