Schaller SureClaw Guitar Tremolo Unit Spring Tension Unit

Genuine German-engineered Schaller SureClaw spring tension adjuster unit. Designed to replace standard floating tremolo claw screws, the SureClaw allows fast, precise, and tool-assisted adjustment of tremolo spring tension directly through the back guitar cavity without needing a screwdriver or removing the backplate. Built from heavy-duty steel to maintain stable spring claw positioning, prevent detuning during tremolo use, and simplify alternate tuning adjustments and string gauge changes on locking tremolo-equipped guitars.
