Very rare pedal. Used by Frank Zappa. This is a 70s vintage Oberheim VCF 200 pedal. It has an envelope filter and a switch to select a randomized, intense filter. It has been tested and is fully functional. There are only a few of these in the world, and you rarely see them in Japan. I'm selling it because I haven't been using it recently. Accessories: Main unit only Please note that this is a used item, so no returns or refunds are accepted.
