Gotoh Tremolo Unit Removed from k.nyui's Stratocaster. I had no complaints, as I only wanted to change the string spacing. I think it's a beautiful item with no scratches or cloudiness. String spacing 11.3mm, mounting pitch 11.2mm It's a standard size that can be easily installed on vintage Fender copy guitars. This is not the cheaper version, but the steel block version with a magnet attached to the block. Please note that due to size constraints, the plate and block may be removed for packaging.
