Kit includes: 1) ResoMax NV2 Tune-O-Matic Bridge w/ String Saver Saddles 2) ResoMax NV Tailpiece From Graphtech: The ResoMax bridge is made from our ResoMax alloy. ResoMax is a lightweight, high strength, and full of harmonics alloy that will leave your guitar dripping with tone. It comes preloaded with String Saver saddles to reduce string breakage and improve tuning stability. All ResoMax bridges feature our patented magnetic lock to the steel posts that come with it. This is a great option to upgrade or replace the existing tailpiece on any electric guitar that currently has a standard tune-o-matic bridge and tailpiece combo. Stop tail piece is equipped with AutoLock, this tailpiece magnetically locks the bridge to the body of the guitar without a tool making re-stringing a breeze. I'm selling a Gibson Les Paul, Graphtech Ratio Tuners (3x3), a Vola OZ, Bareknuckle pickups, amps and other accessories. Will discount the more you buy!
