This listing is for one (1) Fender Musicmaster or Duo Sonic II bridge saddle. This is for the Post mid 1964 II series with the revised bridge assembly. These were a funky design in that they are slightly different from Telecaster saddles in every way. Smaller diameter, longer length, and different screw threads. A very hard to find part when you need one. Came out of the stock of a defunct Fender service center. May be NOS or lightly used. All screws turn freely.  Sold as is.
