Why Guitar Monkey Bass machine heads?

Our Guitar Monkey Bass tuners fit any bass guitar with a 13.8mm to 14mm hole diameter in the headstock and screw tab holes at 90 degrees, although you can of course also drill new screw holes.

Our bass mechanics are characterized by their compact design and low weight. The gear ratio of 20:1 guarantees excellent handling and precise tuning. Tuners with an open design are often susceptible to dirt and wear, but not our bass tuners. Because of the closed design, our bass mechanics are maintenance-free (no oiling required) and are not susceptible to contamination.

We offer our bass machine head sets for all arrangements on the headstock. We therefore offer over 48 different set variants - simply unbeatable and available for every type of bass guitar. This means you don't have to buy your tuners individually; you can find exactly the right set for your bass guitar at Guitar Monkey, regardless of whether it's a 4- or 7-string bass guitar and regardless of the arrangement of the tuners on the headstock!
