This Set of 6 in line right handed official Fender Locking Tuners has vintage style buttons and will fit most modern style Stratocaster and Telecaster guitars with dual pin mounting configuration. The locking system is operated by a thumb screw on the back of the tuner for quick and easy string changes and the 6 in line sets have staggered string posts (3 long, 3 short) to provide the correct string tension over the nut and improve tuning stability. The enclosed gears feature a 1:18 gear ratio for accurate tuning.
