Used one (older KC500) as my "Swiss Army Amp" for years. Used it for church a lot, ran a POD and an acoustic DI off a Parker Fly, with the XLRs to FOH. Great set up, if a bit oversized. Used as a vocal monitor, as a low volume bass amp, even lent it to a buddy to use as a PA for his very DIY wedding. If I was to do it over again, I'd probably get a proper powered PA speaker and a small out board mixer. Those 150 watts don't go very far against a drum set when you're running bass through it, and it bottoms out pretty quickly with bass drum sounds, IMO. Also had trouble with higher gain guitar sounds and the horn. But to be fair, its a fairly inexpensive unit, and survuved lord only knows how many services, gigs, jam sessions, and a car accident.
