Faster and More Accurate Tuning

Graph Tech's Ratio Locking Tuned Machine Heads offer a revolutionary new experience in ensuring your guitar is tuned more quickly and accurately than conventional tuner designs. Each tuner in the set boasts a custom gear ratio that makes each machine head react the same — roughly one full turn per whole tone. Because each string reacts the same, not only is tuning a more pleasant experience, but nailing alternate tunings is a much faster process. Graph Tech's mission statement is, "To Improve Your Playing Experience." They've nailed it with the Ratio Locking Tuned Machine Heads.

Graph Tech's Ratio technology

Though it's a simple idea, Graph Tech's Ratio technology completely changes the way you tune your guitar. All six strings are outfitted with gear ratios that ensure you attain the same response from your wound low E string as you do your unwound high E. No matter what string you are tuning, you'll notice that one full turn of the tuner equates to roughly one whole tone pitch change. The Ratio technology makes nailing your pitch much easier and faster. And you'll love how fast it is to get to Drop D and other alternate tunings.

Easy installation with no drilling

One of the greatest benefits of the Ratio Locking Tuned Machine Head system is that they install onto your guitar's headstock without any drilling or other destructive procedures and are completely reversible. Graph Tech's InvisoMatch mounting plates ship with the tuners. The machine heads mount directly to those plates and aren't screwed into your instrument. As their name would suggest, the InvisoMatch mounting plates are completely hidden by the Ratio Locking Tuned Machine Heads and offer a sleek, low-profile look.

Graph Tech

Graph Tech has made it their personal mission to supply the products that will make your instrument play better, sound better, and perform better. From the company's popular String Saver saddles to their TUSQ string nuts that can be found on countless manufacturers' guitars, the company's products are a mainstay in the guitar and bass industry. Just about every player at Sweetwater owns something created by Graph Tech, because — like their mission statement demands — they never fail to improve our playing experience.

These are absolutely the best locking tuners on the market. The accuracy in tuning is extremely precise. I installed these on my Godin Session and they are fantastic. I will be installing these tuners on all my guitars. Do not hesitate to buy,

Love um

I was looking for quality machine heads to replace my korean made stock non-locking tuners and I seen drastic improvment right away in my tuning stability. I have this on a strat style body with a super V bladerunner bridge with A LOT of float set and installing the locking ratios got my axe keeping excellent tune even with heavy forward and back whammy action.
