I love the sound of my Roland KC 300. LOVE it. I love the fact that the tone from the amp is actually the tone of the instrument, minus the typical "small bass amp trying to be a big-sounding one" type of eq bias.
Use this amp selectively for gigs. With gigs for low stage volume, it's great. With a drummer who isn't a hard hitter, or expecially one who plays with brushes, this is a good amp to use, particularly as it has outputs than can be run into a main PA.
The price is good. Mine was bought new, and is worth every penny. Great for any instrument but electric guitar.
