The original MV Mastery Vibrato model features a unique shaped body plate and is for new builds only. All the same guts as in other Offset Vibratos but with our body plate design that has a different wood screw location. What many artisan builders use as original equipment hardware. This model is not intended for retrofitting on a standard Offset-style footprint. Solid stainless string and body plate are hand straight-line sanded to a beautiful finish. Parchment tip and solid stainless mounting screws included.
