“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 tone, 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.

“The Guitar NutBuster® is a game changer!

 Not only does it keep my Explorer in perfect tune it adds sustain and sound quality.

 Very happy with the results!”

– Dave Mizrahi, (Guitarist) Marina Del Rey, CA

7-String Guitars

* The Guitar NutBuster® is extremely versatile and can also be used on a 7-String guitar with fantastic results *

The first (6) strings (the most problematic to have tuning problems) are stabilized as normal through the Guitar NutBuster® while the 7th bass string (the least problematic) passes along on the side allowing for quick, on the fly bass string alternate tuning adjustments.

(A 7-string Guitar NutBuster® version is currently in development with a target release of Spring 2022)
