Mastery Vibratos feature our unique arm housing that is machined from a single block of solid stainless steel and has an internal stainless steel spring plunger that allows you to adjust the stiffness of the vibrato’s arm rotation to your preference. The arm housing is threaded into our spot welded doubler/string plate and is secured by a self-locking cone point set screw into the doubler plate. The arm itself is vintage-spec brake formed (not curved) with zero free play and has a threaded outer end with parchment tip included. No internal nylon plastic components are used.
The fulcrum, doubler and string plate feature vintage-spec metal thicknesses and are un-plated solid stainless steel to ensure edge and thickness accuracy.
