GrooveTech Soundhole Truss Rod Wrenches

Available at Acoustic Centre Melbourne

The GrooveTech Soundhole Truss Rod Wrench makes truss rod adjustments on acoustic guitars a breeze, offering musicians a practical and efficient solution for maintaining their instrument’s neck tension. Unlike traditional wrenches, the GrooveTech wrench is designed specifically for acoustic guitars, providing access to the truss rod through the soundhole. This clever tool allows easy adjustments even in tight spaces, ensuring you can fine-tune your guitar’s neck without hassle.

With its precision ball-end tip, this truss rod wrench fits most acoustic guitars, while the extra length on both segments of the blade provides improved leverage and easier access to nuts that may be blocked by braces. The oversized handle gives you a confident grip, making it easy to apply the necessary torque for adjustments. Available in two sizes, it’s compatible with most brands, with Martin guitars post-2007 (except the Modern Deluxe series) requiring the 5mm wrench and most others needing the 4mm wrench.
