TUNING
PRECISION
ON EVERY STRING!
WHAT ABOUT IT?
RATIO for bass machine heads is a new tuning system that increases the predictability and efficiency by taking the guess work out of tuning.
On conventional bass machine heads, each string’s machine head has the same gear ratio; however, each string has a unique string diameter, causing each of the strings to react differently to the turn of the machine head.
With the new RATIO for bass, each string has its own specific gear ratio,
so that every string reacts the same to the turn of a machine head.
HOW DOES IT WORK?
Since each string’s core diameter is different, a specific gear ratio for each string was researched and developed to ensure that each string reacted the same to the turn of a machine head.
The result for a 4 string bass is a gear of 48:1, 36:1, 25:1, and 23:1 for the E,A,D, and G string, respectively. This system has created an even tuning experience that assures you that once you know what it feels like to tune one string, you will know what it will feel like to tune the rest of the strings. The easy-to-install system is available in classic “clover” style buttons or with the more contemporary “Y-key” style buttons. The “Y-key” buttons are available in chrome or black finishes. The Ratio for bass machine heads are also available for 4, 5 and 6 string basses in most headstock configurations.
1 TURN = 1 FULL TONE
Higher gear ratios on the thicker core strings and lower gear ratios on the thinner core
Exclusive double envelope, hardened steel gear for strength and precision on higher gear ratios.
The simple genius of RATIO multi-geared machine heads RATIO matches the gear ratio to the core thickness of every string so that every string responds to precise tuning adjustments.

“I like String Saver saddles because they save my strings from breaking...I’ve been using them now for at least 10 years, if not longer, and I’ve noticed a significant decrease in string breakage... I hardly ever break strings anymore.

“Graph Techs new Bass Ratio tuners are amazing!.These baby’s are smooth, precise and keep me in tune all night.What more do you need”

"Thanks so much for the String Saver Saddles. I have them on my stage guitars and this past summer while touring with The Guess Who, I never broke one string! I like to leave my strings on indefinitely, I happen to like "dead" strings, as they give me more sustain and help me get 'my sound' so Graph Tech is in my loop forever. Thanks for the great product; it's one that's long overdue for the axemen of the world."
