Violinist and electric violin historian Ben Heaney (deltaviolin.com) posted a short but very high quality studio recording to YouTube of the original production prototype Fender electric violin from 1958. The recording is an extraction of the violin track from a professional album recording session Heaney played on. Heaney, tells us "in the video you get to hear the instrument through a Fender twin mic'd front, back and overhead ambient. No further processing or EQ but with some verb."     For a further sample of the '58 Fender violin's tone, check out Heaney's recording of Telemann and read about his Fender tone experiments here.
