Future Retro XS - Rare Semi Modular

Purchased right before I went into building a modular system and just stopped having a need for it. Its been used lightly but only noticeable marks are on the rack ears. Been in a smoke free studio. I have turned it on 2 times in the last 12 months. Thats how much use it has received. Hopefully someone can give it a nice home where it may be played with on a regular basis. :)

 The XS is a true semi-modular analog synthesizer with a universe of sonic possibilities just waiting to be discovered. Our versatile design allows it to be used as either a rackmount or desktop instrument, and its compact size makes it ideal for musicians on the go.
