Made for small concert halls, I bought it to use with my electric drum kit. I no longer have the kit, and I don't need it for anything else, so it's time for it to go. It's never been used above half volume, the speakers sound as good as the day I bought it. What else would you expect from Bose? There's an input for a mic, one for a guitar, one for an Auxiliary line-in, and a red/white input. Asking $500 obo
