Retro-style open Ratio calibrated machine heads for vintage-style electric guitars that use 3+3 side tuners.
The Graph Tech Ratio 3+3 Retro tuning machine heads deliver predictable, precise tuning, on every string. Each string reacts the same to any tuning adjustment. Graph Tech has balanced the gear ratios to each string, which simplifies the tuning process. With Ratio tuners, a half turn is a semi-tone. The Graph Tech PRN-4424 is a right-handed set of open Ratio calibrated machine heads that feature a retro look and are made for vintage-style electric guitars that use 3+3 side tuners.
As a note, Graph Tech’s retro tuners are made to a vintage specification (for 11/32" peghead holes) and will not be a direct replacement for a modern tuner.
