The Wilkinson VS100G is a knife edge vibrato where the front edge is being held in place by two posts that are threaded into two studs (your typical fulcrum spring-balanced knife edge pivoting system). Height adjustment of the bridge is achieved by turning the studs in or out. The saddles on this tremolo are solid bars and are height adjustable by 2 allen posts. Intonation adjustments are done by forward and backwards movement of the allen screw through the rear end of the saddle. Slight sideway adjustment is possible to allow for various neck widths and pickup pole piece alignment.
The saddles, arm and studs are made of stainless steel and it has a detachable arm with a nylon adustment collar.The string spread on this bridge is 2-1/8" (54mm). It is usually advised to use this tremolo in combination with locking tuners and an LSR Roller nut or graph tech nut for maximum tuning stablity.
There is also a Wilkinson VS100N version which is basically the same tremolo with the addition of locking studs.
