The S series has long been admired for its design, but some players prefer the simplicity of a non-locking tremolo. The SV was created to satisfy the professional player who wants a more versatile solution. The SynchroniZR non-locking tremolo uses the same smooth ball bearing mechanisms that have made the ZR bridge so popular. The SV also comes equipped with the True-Duo pickup system for superior tonal variety from the single coil and humbucker universe.
