FENDER DUO SONIC bridge, believed to be from around 1965. Please note that the 1st string height adjustment screw is missing. However, it has been replaced with a compatible set screw of a different length in black, as shown. Please confirm. Swapping the higher 3rd and 4th string saddles might reduce any noticeable difference. Sold as is, no returns or cancellations. Please examine the images and understand the condition before considering a purchase. Thank you for looking.
