Please read the following description and profile. [Manufacturer] GOTOH [Model Number] 510FB [Condition] Junk This is a bridge that was attached to a guitar I bought used. Stud bolts are included, but the anchors to be inserted into the guitar are not included. The reason for the junk condition is that the 3rd string sounds dead even with a new string. I replaced it with a different roller bridge and the problem was resolved, so I think the issue was with this product. I think the grooves probably need to be re-cut. However, I was using the guitar this bridge was on for down-tuning. The strings I was using were 12-56, which are much thicker than normal, so it's possible that the grooves and string thickness didn't match, and that was the reason. I haven't confirmed what the sound would be like with 09-42 or 10-46 strings. In any case, this is the nature of the product, so it is being sold as junk. Please purchase with the understanding that the grooves may need to be re-cut or the saddles replaced. There is dirt and cloudiness. Shipped via Rakuraku Mercari.
