Nice old vintage Schaller Camlock tuners (Phase I) from 1985 3X3 set. Instead of saying PRS on the back these have the Schaller "S" and say: Made in W Germany. Nice hard ware, That was saved for a project guitar that changed direction decades ago. They are complete, chrome finish and working fine. These lock the string with a cam and a string clincher and which has a pointer on it so you tell if you are in tune you can tell by looking at the tuners. (That's what PRS received the patent for.). Includes washers and hex nuts but, the screws that screws thorough the tabs were reused on the doner PRS guitar. These make string changes a breeze. (I have "quick change" tail piece also in nickel for a separate sale.) Please leave name and phone number in email response.
