This is essentially a take on Fender’s HMV bridge, except with a 5 hole mounting pattern for top load basses, and is a direct drop in for Fender MIM and US Vintage Reissue models. The plate and “tailpiece” are actual machined brass unlike some cheapo eBay import “hi-mass” variants, while the saddles are of the single grooved zinc variety. Another cool thing about these bridges is that it won’t require a neck shimming (such as is often the case with BA style bridges) as the base plate is of a standard thickness. This is a direct replacement for any top load Fender 5 hole bent plate bass bridge and incredibly well made: Asking $21 shipped CONUS/PayPal
