Listed briefly a couple years ago and recently re-listed.

Selling a vintage QUAD MODULAR FILTER. Only 97 produced worldwide. Shipping available. You could buy 2 new Sherman Filterbank Dual Racks for 3000 and use 4 wall-wart power supplies to power it, or this vintage Sherman beast with 2 original Filterbanks, 2 Filterbank-2 prototypes and many unique features all powered by a proper single IEC cable.

This is a modular synthesizer in its own right. It has many audio-rate sources, including all of the self-resonating voltage controlled multi-mode filters which can generate richer complex waveforms than just standard sine waves and of course all of the hyper audio-rate Low Frequency Oscillators.

Reverb and additional fees are very high currently. Can’t sell for less than it’s worth.
