GOTOH Wilkinson VSVG tremolo bridge for guitars. This vintage-style pressed saddle is designed by Wilkinson, allowing for a more solid fixation of the bridge plate and saddle, reducing the loss of string vibration transmission. In addition, the string-through holes are offset from a straight line to optimize the tension balance. It was attached to a guitar I purchased, but I'm selling it because I've returned it to the original parts. The brown bag contains the arm, springs, and six screws.
