The original model, manufactured by Rush himself, seems to have been used by a small number of bands, hence its obscurity. The Beatles had two, psychedelic pop act Pinkerton’s Assorted Colours are said to have used one and Rush remembers delivering two to Cecil Sharp House, the English Folk Song and Dance Society, where The Shadows were rehearsing, although no trace of its barely controllable, harsh distortion is discernible on any of their recordings.
