"Legendary expander much sought after created by the Fernandez brothers Ruben and Serge. There have been fewer than 800 hand made from '79 and this particular one is in superb condition. Kept in a smoke free studio its entire life anyone looking for something collectable and mint will appreciate this for years to come. Superb for electronic music and amazing for rip roaring bass sounds...the tone on these are immense!

The 19" 3 U space unit features a Ring Modulator, Envelope, a VCA, an LFO, Mixer with 3 inputs and 1 output.
