Since its introduction in 1954, this classic design is the most copied guitar vibrato bridge ever. The design is so simple and eminently usable it is a challenge to improve on it, but improve it Wilkinson did!Faithfully reproducing the size and weight of the original, this is a direct retro-fit for the "real thing" but with the added benefit of a push-in vibrato arm rather than the troublesome original screw-in type. Wilkinson also staggered the string holes in the sustain block allowing the strings to follow the natural intonation line of the saddles, keeping the strings' "angle of attack" over the saddle's intonation point more consistent, eliminating annoying string "hang-up" giving unrivalled tuning stability. Completing the assembly are the bent steel saddles built from the same gauge steel as the originals to retain the "vintage sparkle" that this bridge has become famous for.Specifications:- Hardware colour: chrome- Saddle material: stainless steel- Block material: steel- String spacing: 10,8mm- 6 mounting screws, push in arm, handle and 4 springs are included
