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 B 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.

Reviews

Smooth, precise, and better than the originals
I had to replace the original tuners on my bass, and these Graph Tech Ratio tuners were a total upgrade. They tune very smoothly, hold tuning extremely well, and the Ratio system really makes a difference. The black finish looks excellent, and installation was easy. I'm also very pleased with the customer service and the fast shipping of the product. Completely satisfied.
Great product at an affordable price!
Great upgrade for my Spector Legend 5 string bass. No adjustments or modifications needed, perfect fit straight out of the box. These tuners are definitely worth the price. I haven't had a need to test the down tuning capabilities as described, but love these beefy stellar tuners! Highly recommended!

Super stable ratio specific tuners
Game changer!
I love Schecter but in this particular instrument their tuners are not stable and tend to brake and fail.
These tuners are ROCK SOLID and being ratio specific gives them that extra level of control in fine tunings that other do not have.
Music background: Amateur musician working on getting to the next level.
5 string bass tuning machines
The machines fit perfectly. Installation was easy and straightforward. I can already tell their quality is better than the machines I purchased from another music equipment vendor. Money well spent!

Very worthwhile upgrade for the Yamaha TRBX505.
Do not hesitate as these are a direct replacement for OEM tuners, no drilling/adapters necessary so I incorporated installation with a string change. Maybe 10 minutes tops and all that's needed is a small Phillips head and a 15mm wrench. To be honest I thought drilling holes on the back of the headstock was going to be a must. Well until recalling this is not a 4-in line but instead a 3+2, and if you put them on the correct side then no new holes needed, duh. The weak OEM tuners are about the only flaw with the 505 and these solve the issue.
