Behringer Poly D Polyphonic Analog Synthesizer. I bought this just over a year ago and used it only a handful of times. With the exception of a little dust it is in excellent condition and works perfectly. Please don't bid if you haven't done your research about this product because there is a learning curve to a synth like this. It is often these days that ebay buyers want to return simply because of buyers remorse. I will not be returning this synth unless it is somehow damaged in shipping which would be hard to believe being I am shipping it in the packaging it came in. Also, it comes with the original power source, manual and box. Don't mean to sound like a jerk but I am over being treated like Amazon. Thanks, Dave
