Selling my two Volcas as a set: Keys (Analog Synthesizer) and FM (Frequency Modulation Synthesizer). Comes with the instructions for the Keys and one power cord. Both can operate on batteries.

They work just fine and they sound great via the line-out headphone jack — though the built-in speaker for the keys is out. Love these a lot, but I need to thin out my studio. These wonderful portable synths could be yours today!
