Tune Voodoo guitar string guide – A bit of background

Happy holiday greetings to all you fellow guitar players! I’m glad you found your way to this brand-new blog. In this first post, I will explain a bit of background of this cool-looking guitar string guide that I recently invented with a friend of mine.

A few months ago, I finally managed to get my hands on a Gibson Les Paul, which has been a dream of mine for as long as I can remember. I was so excited when it finally arrived, but I have to say that the frustration I faced when the bugger just didn’t stay in tune was… aaaarrr… quite something. I could basically play only one song with one-step bends on those strings and then I would have to tune the guitar all over again.

After spending an absurd amount of time on google I found a ton of information on what causes the tuning issues, but not too many solutions for fixing them with style. Surprisingly I also found a ton of controversy on whether this problem even exists or not. I have formulated a theory on this strange contradiction, but that will be a topic for another blog post soon.

Problem: how to keep the guitar in tune even if you are bending like a rock god?

This YouTube video from Darrell Braun explains the problem well.

To sum up, the reason for this type of guitar tuning issues is basically just physics and more precisely the friction between the string and the nut. The guitar’s headstock is in 17-degree angle which causes huge vertical friction to the nut. Positioning of the tuners cause additional horizontal friction to the nut. Now when bending the string, the string gets stuck into the nut, causing the string to get out of tune.

Solution: attach a guitar string guide to the truss rod cover

Darrell’s request for ideas how to keep the aesthetic beauty of Les Paul while increasing it’s tuning ability got stuck in my head. So me and my friend came up with this simple but practical truss rod cover.

As you can see from the picture, we added a string guide on top of the truss rod cover to guide the D and G strings directly from the nut. This solution removed the friction problem from the nut but the very first version was not quite enough to solve friction in the string guide too. Quite soon, we solved this issue by inserting metal spacers inside the truss rod cover to minimize friction.

Challenge: to create a more universal, eye-catching guitar string guide

Now this new truss rod cover was specific for Gibson, but what about other guitars with 3L/3R machine heads on the headstock but totally different truss rod covers? We went back to the drawing board and came up with a version that is attached to the top of the truss rod cover with only one screw. Little bit of innovative design, dash of rock attitude and, voilà, the Tune Voodoo skull was born.

You can see the metal spacers inside the eye sockets to minimize friction.

Goal: to create an empire and gain world domination on tuning solutions

After developing and testing several versions of the Tune Voodoo guitar string guides, we are now happy to announce that we are currently fine tuning (pun intended!) and finalizing the product for sale.

The initial feedback from our testers has been overwhelmingly good, our patent is pending, and we are looking for funding for this project.

At the moment we are especially looking for more beta testers, so sign up for our newsletter and become a part of this exciting journey.

    • Hi Richard, for you the solution would be the skull version. You can screw it on the upper screw hole that is currently holding your truss rod cover in place.
