Allen ball end for easy access! Our special right-angle wrenches provide clearance under the guitar's braces for adjusting the truss rod through the soundhole.
Our veteran guitar technicians developed these high quality steel truss rod wrenches for the repair shop. The length, comfortable rubberized handles, durability, and variety of sizes let you perform truss rod adjustments more efficiently.
The 4mm wrench is for Hot Rod truss rods. #6110 works for pre-August 2007 Martins; #6114 is for Martins made afterward.
These tools are available in our money-saving Truss Rod Wrench Set.
