“Take Control of Tuning Problems!”

The Guitar NutBuster®is an attachable, user-installed, completely non-invasive

Locking Tune Stabilizing System that offers significant control over the most common tuning problems.


It’s simple, easy-to-use and delivers immediate results. The Guitar NutBuster®is a patented All-in-One

floating and suspended system that attaches directly to your guitar’s strings, safely and with no damage,

and instantly transforms a stock whammy bar equipped guitar into a Tune-Locking Powerhouse!

The Guitar NutBuster®is also extremely advantageous for hardtail (non-tremolo) electric and

acoustic guitars: it adds sustain and  fine-tuning capabilities, making

the Guitar NutBuster®a great tool for all guitar players!


What’s it worth to finally remedy your tuning problems, have “tuning peace of mind” onstage,

or reconnect with a beloved old guitar that you couldn’t use the whammy on? And, if you want,

there’s nothing to say that you couldn’t easily take it off and try it on another guitar!

The Guitar NutBuster®does its job all while remaining a totally

non-invasive mod which is pretty rare for hardware!


The Guitar NutBuster®is proudly designed, manufactured and

assembled to the highest quality and standards in the USA.
