Graph Tech PRB-4401-C0 4-In-Line Bass Ratio Open Back Classic Clover Leaf Button Tuners

Upgrade the tuning process for your bass! These Graph-Tech Ratio tuners feature a four-in-line configuration with clover-style buttons.
Graph Tech's calibrated & synchronized tuning system makes tuning and re-tuning your bass faster and more intuitive. Tuning on the fly has never been easier! Each string position has its own calibrated gear ratio, so every string feels and reacts the same to any tuning adjustment.

One full rotation of any key results in a one full tone pitch change (give or take). From Low E to G, the gear ratios are 48:1, 36:1, 25:1, and 23:1.

In order to achieve the higher gear ratios, ratios are the world's first machine heads using a double envelope gear design with a hardened steel gear. Amazingly smooth and super strong.
