An almost ubiquitous eurorack module full of physical modeling goodness and painfully beautiful soundscapes. Essentially self-contained oscillator with a simple envelope, secret modes, and even Reverb. If you haven't had one of these yet, you should. I, however, am parting ways to downsize. Sold As-is. Comes with power and screws.
