The Wilkinson WV6 series provides the unsurpassed ?tone transfer? of a six screw pivot system with the smooth fulcrum action of a two pivot set up. With the unique 5+1 pattern one hole is used to locate the vibrato laterally while the five remaining elongated slots eliminate the chance of screws binding in the holes. The result is a tremolo that returns to the original position like no other. Solid steel sustain block Available in Black, Chrome, or Gold Finish. Key dimensions: Center to center post - 56mm String span - 54mm String pitch - 10.8mm. FREE Shipping within the 48 States of the continental USA.
