OVERVIEW

Reaches even the most recessed nuts.

Most acoustic guitars require truss rod adjustment through the sound hole, sometimes past one or two braces to an unseen nut. As a result, normal hex wrenches are not practical. CruzTOOLS GrooveTech Sound Hole Truss Rod Wrenches were designed specifically for this application, with blade length optimized to fit within the sound hole opening and long enough to reach even the most recessed nuts. A specially designed ball-end tip allows easy seating into the nut, and a pro-grade alloy using tight manufacturing tolerances prevents any chance of damage. Finally, an oversized screwdriver-type handle provides confidence when making truss rod adjustments.

Two sizes are available: 4mm fits most makes of guitars, while 5mm is primarily for Martin guitars.

FEATURES
Designed specifically for acoustic guitars with truss rod nuts inside the sound hole
Special ball-end tip allows for easy insertion into truss rod nut
Professional grade
Screwdriver-style handle provides confident grip
Two sizes 4mm and 5mm fit most acoustic guitars

              Comments about CruzTOOLS GrooveTech Sound Hole Truss Rod Wrench:

              I will agree with other reviewers that this price seems a little high. However, there are times, and this was one of those times, that a person has to have the right tool for the job. I needed to adjust the truss rod on my Martin to eliminate some fret rattle, and I quickly found out that not just any 5mm hex key would do it. The CruzTool did the job without me having to remove all my strings and re-string my guitar, nor did I have to take it to someone and pay them probably the same amount of money, plus I now have the tool I need when the situation presents itself again.

                    The single, minor issue I have is that if the handle side was about 1/4" shorter, it would fit well in the accessory compartment in my case. The case is aftermarket (SKB) so this could just as easily be the cause instead of the tool.
                    Functionally, the tool works perfectly. It literally took me about 2 minutes to get my neck much more playable.
