The Joe and I were jamming a bit last night and this started happening. Recorded on the iPhone through a crappy practice amp.
The Saturn is a tunable ring modulator with a dirt circuit. Played lightly you get lo fi video game like tones when you dig in, or stack a fuzz on it, you get raging awesome octaveish sounds and piles of rock glory. It's a crazy fun pedal to play.
There's an expression jack on the side that will let you tune the frequency to whatever key you are in on the fly.
