Optigan 35001 Stereophonic

This optigan has an onboard amplifier with two channels, one for the accompaniments and effects (brown keys to the left) and one for the keyboard sounds. All of the optigan's optical discs had a full keyboard set on it, plus rhythms and 5 effects which could be read by any instrument in the Optigan range, by Mattel. The discs we used on this video were 'Big Top Marching Band', 'Rollin' Easy' and 'Big Band'.
