uMod II (Used)

The µMod II is a multi-function module designed for combining audio or CV signals in a variety of ways. Apart from a versatile ring modulator / four quadrant multiplier it also performs analog logic functions useful for generating new combinations of waveforms. 
The principle of operation is to take two signals, called X and Y, and produce a series of output signals that are derived from the sources using a variety of analog methods.

This used unit is in good condition.
