RATIO® - Calibrated Machine Heads incorporate different string gauges into the tuning equation.
From Low E to G - 36:1, 30:1, 20:1, 18:1.
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.

A bit expensive compared to competitors, but absolutely worth the extra money.
The only downside for me, was that the connection plates didn't match my original Kluson Waffle back.

I have Graphtech tuners on my three guitars! They are the best of the best, in my opinion! These machine heads keep me in tune better than any tuners I’ve ever used! Worth every penny if playing in tune is a non-negotiable requisite for your playing satisfaction!

They are very well made, light, direct replacement for vintage, and quite nice to look at. Finally a high quality tuning machine which I don not mind spending extra on. I don't miss no locking on these as the tuning stability improved a lot on my tele. Will replace my favorite guitars with these for sure.
