The original MV Mastery Vibrato model features our unique shaped body plate and is for new builds only. All the same guts as in our 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. Vibrato arm, parchment tip and solid stainless mounting screws included.
