This super-trippy 1972 advertisement for the Wurlitzer’s Orbit III reveals that it ‘may just change your mind’!

The Orbit III had a lot of typical 70’s electric organ features – transistor organ sounds, preset beats and a tape recorder.

But it also included a basic mini-keyboard monosynth – which must have been pretty trippy at the time!
