Faster, More Accurate Tuning

Get to know them!

Graph Tech's Ratio 6 In-Line Electric Guitar 2-pin Machine Heads offer a revolutionary new experience in ensuring your guitar is tuned more quickly and accurately compared to 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." Here at Sweetwater, we agree that they've nailed it with their Ratio Tuned Machine Heads.

Innovative 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 which 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 Tuned Machine Head system is that they install onto your guitar's headstock without any drilling or other destructive procedures. They are also 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 Tuned Machine Heads, offering a sleek, low-profile look.

Graph Tech: play better, sound better, perform better

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 promises — they never fail to improve our playing experience.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
