The Mastery OMV Offset Vibrato is a meticulously engineered upgrade for offset-style guitars, offering unparalleled tuning stability, tonal enhancement, and playability. Built to exacting standards, it features Mastery’s proprietary full-contact fulcrum plate and a vibrato arm housing precisely machined from a single block of solid stainless steel for exceptional durability and smooth operation.

At the core of the OMV system is a custom pre-set high carbon steel spring, delivering responsive and expressive pitch modulation while maintaining tuning integrity. The vintage-spec, brake-formed vibrato arm is crafted from military-grade 303 stainless steel and paired with a parchment tip, blending classic aesthetics with robust performance.

Both the string and fulcrum plates are precision-machined after brake forming to ensure the correct downward break angle, enhancing harmonic overtones and clarity across the tonal spectrum. The result is a more resonant, piano-like chime that brings out the full potential of your instrument.

Finished with hand-sanded solid stainless string and body plates, the OMV is visually refined and built to last. Installation is straightforward—no modifications required—making it a drop-in upgrade for any standard offset vibrato footprint, including new, vintage, and imported models. Designed for discerning players, the OMV is the definitive choice in offset vibrato systems.
