This is a widely used 5-point mount bass bridge, making it easy to install on Fender-type Precision Basses and Jazz Basses. You can freely adjust the string spacing between the 1st and 4th strings from 17.4mm to 20.6mm to your preference. There are some minor scratches, but it's in relatively good condition. The wrench and screws are included, but the box is not. Thank you for looking.
