Category information

If your bass guitar needs new machine heads, Bax Music is your go-to store. In this department, you'll find tuners for both acoustic and electric basses.

Bass Guitar Machine Heads

There are various reasons for swapping out one or more machine heads. Whether you're dealing with a worn-out set, a single broken tuner or you simply want to enhance the tuning stability of your bass, we've got what you need.

Black, Chrome or Gold Finish

So they can match the hardware of your bass, machine heads are available with various different finishes. In addition to traditional finishes like chrome and nickel, you can pick up black, gold or even black chrome bass tuners. Before you load any into your basket though, you'll want to make sure your new tuners actually fit, so always check to see if the shaft has the right dimensions, the mounting hole diameter matches and whether the mounting screws line up correctly. If everything checks out, installing a new set of machine heads is as easy as can be. Also, if you're looking for a specific set of tuners that you can't find listed here, then don't hesitate to fill out our Product Request form. We're happy to try and source them for you.
