AVR-II Tune-o-matic Bridge Gold. The Advanced Vintage Replacement II is the exact replacement for the bridges found on older or vintage electric guitars originally fitted with ABR-1 style bridges. The AVR-II locking model has the complete appearance of the vintage part, but has many upgrades including more intonation range, and saddles that are "engineered in" solid, preventing "lift" against the retainer wire. Retrofit for most Vintage and reissued USA guitars without modification. Extra tight construction eliminates rattles and improves sustain.
