This is a one-of-a-kind CS70M with mods by the legendary Severed Machines () This is the only CS70M in the world with Brilliance controlled by buttery-smooth aftertouch (switchable on and off with the Output Switch) and the LFO to VCO tapered to produce more musically useful vibrato.

The CS70M is often compared to the CS-80, but it has many features the CS-80 doesn't have, including stereo oscillator output (binaural), a polyphonic sequencer, unison + splits, time x5 button for evolving soundscapes, attack + decay control over LFO rate, dynamic filter FM, ramp generators, ring mod as a modulation source, 3 bucket brigade delay ensemble (VP-330 string sounds), and of course, fully-editable patch memory!

This particular one is in incredible shape aside from a few minor scars and a small piece of the plywood missing on the left side (see photos.)
