i purchased this for 42.50 shipped. looking for 35 shipped. this is unused. it has adjustable string spacing and is a top load or string through bridge. it is intended for the 3 hole fender mounting, but if you use it as a top load bridge you can use any of the string through holes to mount it as well. some of them are bound to line up with whatever bass you want to install it on. i have one of these bridges on my nordy 5 string jazz. i bought this one to put on one of my basses, opened it and then didnt use it. again, looking of 35 shipped.
