Abstract
A tremolo apparatus is provided having a stationary frame, a moving frame, at least one linear guideway, a string retainer, and at least one spring. The stationary frame is configured to be affixed to a planar surface of a stringed instrument. The moving frame has at least one ramp with a flat segment and is guided for oscillation relative to the stationary frame. The at least one linear guideway is provided by the stationary frame or the moving frame and supports the moving frame for oscillation. The string retainer has a plurality of string capture bores and engages with the ramp surface to carry a plurality of strings reciprocally as the string bar rides the ramp surface and reciprocates to alter tension of the strings carried terminally of the string retainer. The at least one spring is interposed between the frames to position the string retainer within the flat segment.
