The baseplate of hardened steel and the solid spring block of the Schaller Vintage Tremolo ensures an outstanding sustain. The Roller bridge saddles fix the strings in their optimum position. It is also a perfect replacement for Fender® Stratocaster® tremolos with standard 74.3 mm (equivalent to the distance between the height adjustment screws). Tremolo mounting is done with special mounting studs and threaded metric inserts. These are provided with a fine thread.
