Mellotron M300

Discontinued 1970
Released 1968

A single-manual attempt to shrink the Mk II, with 52 keys, no speakers and new, brighter recordings on two-track quarter-inch tape. The tape format made it unreliable, so tapes charged up and wrapped round the drums. Only a few dozen were made, but its solo-violin and two-violin strings are distinctive: listen to early Barclay James Harvest and Gentle Giant.
