Sound Hole Truss Rod Driver 4mm

GTECH-gtaw4

€14.90

Acoustic guitar truss rods need adjustment just like electrics, but manufacturers sure don't make it easy. Access is typically through the sound hole, sometimes through a brace to an unseen nuts.

Truss Rod Driver Cheater

GrooveTech

GTECH-gttrc2

€12.90

Vintage-style truss rod nuts have long, thin slots and are made of unhardened steel, so normal slotted screwdrivers will cause damage – as evidenced on many vintage guitars and basses. We developed two screwdrivers specifically for this application. Proper adjustment involves removal of the neck for full nut access, and our Standard Driver provides firm...

Stagehand Guitar/Bass Tech Kit

GrooveTech

String Cutters

GrooveTech

GTECH-gtsc1

Guitar and bass strings are made of hardened stainless steel or nickel with thicknesses as much as 3mm. Ordinary diagonal cutters are designed for soft copper and as a result fail miserably when used on strings. GrooveTech String Cutters were developed specifically for this application, using a proprietary heat-treatment process. Despite its compact...

Mini-Multi™ Guitar/Bass Multi-Tool

GrooveTech

GTECH-gtmm2

At less than three inches long, the Mini-Multi is the world's smallest multi-tool for guitar and bass! Some players don’t always adjust truss rods, so we removed those sizes (don't worry, our popular GTMLT1 Multi-Tool covers them) and took a deep-dive into sizes needed for tremolo systems as well as action, pickup height, and other basic work. It includes...
