Description

The PRB-5320 is a right-handed set of RATIO® Calibrated Machine Heads for BASS that use a 3 x 2 configuration. Every string reacts the same to any tuning adjustment. Predictable, precise tuning, on every string. In order to achieve higher gear ratios, Ratio are the world's first machine heads using a double envelope gear design with a hardened steel gear. Amazingly smooth and super strong.

GraphTech balanced the gear ratios to each string simplifying the tuning process. With RATIO®, a half-turn is a semi-tone!
