A multitool designed for quick adjustments, anywhere
Conceived by Dan Parks, founder of GrooveTech, the 4-in-1 wrench is a multifunction tool designed to speed up maintenance and adjustments on your guitar, especially Fender USA models. When you don't have a full toolkit on hand, this multitool lets you handle the essentials: adjust the truss rod, fine-tune the bridge settings, and work on common screws-all with a single tool.
Each end is designed to meet the most frequent needs: a 1/8-inch ball-end hex key for truss rod adjustments, two hex keys (1/16 inch and 0.05 inch) for bridge adjustments, and a custom Phillips screwdriver tip suited for type 1 and 2 screws (e.g., neck and pickguard screws). Made from vanadium steel, this 4-in-1 wrench launches GrooveTech's CaseTools line, dedicated to essential adjustment solutions to keep within reach.
