5 good reasons for our bass mechanics

20:1 ratio

Our 20:1 translation guarantees an exact tuning of your bass - exactly the right translation.

Lightweight and compact design

Our bass mechanics are characterized by their compact design and low weight. Due to the closed design, they are insensitive to dirt and remain maintenance-free (no oiling necessary).

Suitable for almost all basses

The majority of all basses have 90 degree screw holes for the mechanics, which is why our bass mechanics fit a large number of basses. Of course you can also drill new holes if your bass has different screw holes.

All variations

We offer our Monkey Locks in sets for 4, 5, 6 and 7 string basses. Likewise for all possible arrangements of the mechanics on the headstock. With us you are guaranteed to find what you are looking for - for each of your basses!

quality and packaging

Each individual mechanism is finally checked again before shipping and the result is recorded on our quality card!

Likewise, for us the most sustainable packaging is the one that can be reused, which is why we only use our premium doypacks.

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 lug holes at 90 degrees, although you can of course also drill new screw holes .

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