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.

RATIO Machine Heads explanation video

 

The PRN-4624 is a right-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.

    Killer Tuners!

    Literally installed in less than 5 minutes. Once the fresh set of strings were stretched out, the git stays in tune like nobody's business. I'm not a finesse type player. I beat the heck outta a guitar and made it wish it was never born. These tuners don't lose tune. Pretty amazing. Being locking tuners, string changes are killer fast as well. Highly recommend! 🤘 🤘

    Locking tuners FTW

    Super easy install, plates lined up perfectly, tuners work great! These will be my go-tos for all future tuner upgrades.
