RATIO® patented gear technology
RATIO® - Calibrated Machine Heads incorporate different string gauges into the tuning equation.
From Low E to High E 39:1, 24:1, 20:1, 35:1, 20:1, 12:1.
We balanced the gear ratios to each string simplifying the tuning process.
With RATIO®, a half-turn is a semi-tone!
Every string reacts the same to any tuning adjustment. Predictable, precise tuning, on every string.
The PRN-4624-LN0 is a left-handed set of open RATIO® Calibrated Machine Heads in a retro look for electric guitars that use 6-in-line tuners.
Fits vintage style guitars (e.g. Fender Style).
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.
