    The Graph Tech PRN-4324 are the right-handed sets of open RATIO® Calibrated Machine Heads in a retro look for electric guitars that use 3+3 side tuners.


    Please note that our retro tuners are made to a vintage specification (for 11/32” peghead holes) and will not be a direct replacement for a modern tuner. Please check the specifications below.
