I recently bought a Roland KC 550. It is a keyboard amp, but you can use it for many other things. I bought it for some gigs this summer. It has an XLR microphone input, plus 3 additional inputs. Easily enough to share with a keyboard player, your EWI and your Sax mic. We touched on the subject of amplification way back (not sure if I agree with my opinions from then, oh well).
Sound. It has a nice, smooth sound, and a real nice low end. Two of these together would make a nice little PA system. One makes for a killer amp for those gigs where no one wants to setup and run a PA system. The KC550 has tons of output. I don’t think I ever got past about 4 on it. It never cut out or distorted on any gigs.
Size. Well,
