1,101,050. Electric guitar pick-up. D. H. BALDWIN CO. 19 May, 1966 [30 Aug., 1965], No. 22357/66. Heading G5J. The Figure shows a piezo-electric pick-up for a stringed musical instrument such as an electric guitar. A U-shaped member is slotted 15 along its upper limb 14, the separated cantilever portions thus provided having each a raised notched part 18 to act as the bridge for a particular string. The piezo-electric crystals 20 are in contact with the underside of the cantilevers and are supported by a copper shim 21 slotted between adjacent crystals, a strip 22 of electric insulation which is resilient mechanically and prevents the transmission of transients to the output, and a continuous lower copper shim 23. The output is taken from the two copper shims. To enable a tremolo bar to be used, the bridge is mounted on two conical surfaces provided on the upper sides of knurled nuts 12. In an alternative arrangement (Figs. 5 and 6, not shown), each separate cantilever is provided with an adjustable string carrier which may be adjusted along the length of the string and clamped in position by a screw; the bridge is also tapered transverse to the length of the guitar.
