Faster and More Accurate Bass Tuning

Graph Tech Ratio Bass Tuners allow you to tune your bass guitar more quickly and accurately than conventional designs. Each tuner in the set sports 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." And that's exactly what Graph Tech Ratio Bass Tuners deliver.

Graph Tech's Ratio technology

Though it's a simple idea, Graph Tech's Ratio technology completely changes the way you tune your bass. All tuners are outfitted with gear ratios that ensure you attain the same response from your low E string as you do your high G. 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.

Graph Tech: improve your playing experience

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.
