Stetsbar

He originally designed the device to provide a stable vibrato system that could retrofit to “stop-tail” (fixed tailpiece) guitars such as the Gibson Les Paul with no permanent modifications to the instrument.

The Stetsbar is a floating vibrato system—the pull of the guitar strings is held in equilibrium at the scale length of the guitar by two heavy duty springs anchored to a spring retainer block on the unit's base plate.

When a player moves the vibrato bar up or down, the bridge operates with a linear motion in the same plane as the guitar strings.

An advantage of surface mounting is that installation requires no additional holes or routs in the guitar.

Professional Stetsbar users include Jan Akkerman, Snowy White, Randy Bachman, Elliott Randall, Mike Chain, Reeves Gabrels, Hershel Yatovitz, Cask J. Thomson, John Bohlinger, and Dave Gutter of Rustic Overtones and Paranoid Social Club.
