I'm new to the bass, and need some education about amps. I see Carvin has what looks like a nice little, lightweight, 250W amp that is pretty cheap, the BX250 http://www.carvinguitars.com/products/BX250 With the right speaker cabinet, is there a reason that this would not make a good amp for double bass? What about the MB10 combo amp that they sell for just a little more money? Anyone ever tried one for DB? Just wondering. Thanks.
