GrooveTech GTAW4 Soundhole Wrench, 4mm
The CruzTOOLS Groovetech Soundhole Wrench makes it easy to adjust the truss rod of acoustic guitars thanks to its extended hex blade. No more sticking your arm right inside your acoustic only to drop your allen key! Available in 4mm (GTAW4) and 5mm (GTAW5) sizes.
The item arrived quickly and was the correct size. The tool was easy to use because of the extended arm terminating in a good sized handle making the truss rod turn easily.
