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.

Every string reacts the same to any tuning adjustment. Predictable, precise tuning, on every string.

- KWKristian W.Verified BuyerI recommend this productRated 5 out of 5 stars5 days agoGreat tuners
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.
- MCMarty C.Verified BuyerI recommend this productRated 5 out of 5 stars1 week agoLove These Tuners!
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!

Love these tuners! Smooth as silk. And when my order came in with two #1s and no #3, they responded the next day and shipped the #3. You don't see customer service like this anymore!!
