This is a bridge from an Ibanez j.custom, manufactured around 2009. It is a junk item and cannot be used in its current condition. The screw holes for the small screws that secure the small saddles are stripped in several places, causing them to spin freely. Several screw washers are missing. There may be other issues as well. I don't know if anyone can repair this, but it's not something that comes up for sale often, and there may be people who want it, so I'm putting it up for sale. Please purchase only if you are able to repair it. Thank you for looking.
