“It’s fair to say it’s been a hit among guitar fans looking to eradicate the tuning problems”
Guitar World Magazine
Tuning Made Easy and Stable
Experience flawless tuning with Tune Voodoo™, designed for 3L/3R headstock guitars. Our innovative string guide ensures improved stability and effortless installation, all backed by a money-back guarantee for your peace of mind.

Rock Solid Stability
Tune Voodoo™ corrects the position of the D and G strings for a straight course through the nut slots, preventing the strings from getting stuck in the nut and making the instrument more stable in tuning.

Bold Aesthetic Design
Our portfolio showcases a striking, rock-inspired aesthetic that captivates attention. Customize your guitar with our three exclusive designs: The Skull, The Crown, and The Rock Star.

Easy installation
Installation takes less than 5 minutes. Just replace the upper screw of the truss rod cover with your favorite Tune Voodoo™ design and insert the D and G strings through it.

No marks on your guitar
Since Tune Voodoo™ uses the existing truss rod cover’s screw hole, removing or changing it will leave your guitar in mint condition.
