Graph Tech Ratio Machine Heads – Ultimate Control & Precision


Ratio for bass machine heads is a 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 ration; however, each string has a unique string diameter, causing each of the strings to react differently to the turn of the machine head. With Ration for bass, each string has its own specific gear ratio, so that every string reacts to the same turn of a machine head.

 

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 way to the turn of a machine head. The result for a 4 string bass is one full rotation of any key results in a one full tone pitch change (give or take).  


RATIO® patented gear technology
RATIO® - Calibrated Machine Heads incorporate different string gauges into the tuning equation.

From Low B to G - 48:1, 36:1, 30:1, 20:1, and 18:1.

We balanced the gear ratios to each string simplifying the tuning process.

With RATIO®, a half-turn is a semi-tone!

Every string reacts the same to any tuning adjustment. Predictable, precise tuning, on every string. 


The PRB-5411 is a right-handed set of RATIO® Calibrated Machine Heads for BASS that use a 4 x 1 configuration.
