Behold the rare Joh Mustad AB ‘Tubon’ monophonic bass keyboard, seen above in the hands of Paul McCartney. Remarkably, it was patented in 1967, predating the ‘keytar’ by at least a decade.

❝ The instrument was battery-powered, monophonic and came with a strap so it could be slung like a guitar. It made its mark in the Swedish folk scene of the 60s and 70s and had four presets sounds to choose from: contrabass, saxophone, electric bass, and woodwind. Few made it beyond the Scandinavian frontier, except into the hands of the Beatles and Kraftwerk. ❝ *
