I purchased this amp to use with my acoustic about 8 years ago and have used it a couple of times. It is in excellent condition. It is a peavey KB/A 15 keyboard amplifier and will work with either keyboards or an acoustic guitar. There are two channels on the amp, a level control, low equalization, and high equalization controls for both channels. You also have a headphone jack.
