This is one of the best acoustic guitar amps I've played through. I've used it for guitars and other acoustic instruments (mandolin, etc.). It also is great as a PA and has a separate channel for vocals with simple but good effects. It is a heavy but has a lot of features and is very well built. It is in great condition, no issues with any of the electronics or speakers. It has an AUX input (RCA) which you can volume adjust separately and a good DI (XLR) for larger venues (direct to PA/front of house).
