GrooveTech by CruzTOOLS - Truss Rod Screwdrivers
Vintage-style truss rod nuts tend to have very long, thin slots and are usually made of unhardened steel. The problem with these nuts is that normal slotted screwdrivers will cause damage. Just look at any vintage guitar or bass! GrooveTech by CruzTOOLS have developed two truss rod screwdrivers for this exact application.
Proper adjustment involves removal of the neck for full nut access, and GrooveTech's Standard Driver provides firm contact over the entire slot width for damage-free adjustment.
The Cheater Driver allows quick minor adjustment without removing the neck. Please see their recommendations for use.
Both have oversized handles with extra-long shafts for a firm grip and easy access.
