Wilkinson WV6 Tremolo (Vibrato) Bridge with Wilkinson stamped Steel saddles, 5 + 1 screw holes with knife edges, full size Zinc Block with staggered string holes to make corrections to intonation a simpler job, without putting too much stress on the saddles (see last photo). Push fit Trem Arm for quicker set up, is tightened by a small grub screw at the top right, rear of the trem block. String spacing 10.8mm (54mm E to e), 6 matching colour mounting screws, Allen key, claw & springs. Wilkinson's take on the vintage style tremolo bridge mounting, with another unique design improvement, the screw spacing is a "universal fit". Elongated holes mean the trem will fit on a body drilled anywhere from 54mm (2 1/8") right up to 56.4mm. And as usual, the WV6 sports the narrower string spacing at 54mm (2 1/8") found on most Wilkinson trems. The narrower spacing gives a much more stable string lie across the neck, limiting the possibilities of the E strings slipping off the frets, a great little touch for anyone who likes their hammer ons and pull-offs. Will fit a variety of Stratocaster stryle electric guitars. Wilkinson products, offer the best of classic designs, with clever improvements by really thoughtful & impressive design.
