Gotoh Locking Tuners Nickel (3 per side) These Gotoh Vintage Style locking tuners are a retrofit design to a vintage-sized peghole (8.8mm) that maintains that classic look with no drilling or modification to your headstock They will NOT fit a modern 10mm headstock hole, only a vintage 8.8mm opening. These are 3 per side individual tuners (not on a plate) just like the originals but with the Gotoh Magnum Lock system built into the string post This set comes complete with 3 per side tuners Mounting hardware included.
