RockCare MultiTool for Guitar & Bass — Ultimate USA Instrument Toolkit

The RockCare MultiTool (Inch / Blue) delivers a full suite of maintenance solutions for guitar and bass players. Designed with the needs of USA-made instruments in mind, this 13-in-1 set provides all the essential tools for adjustments, string changes, and quick fixes, all in a robust, easy-to-carry format. Anyone working with imperial hardware finds immediate value in the focused selection of inch-based hex keys and wrenches.

What makes this multi-tool unique?

Unlike most compact multitools, this model includes two removable string winders—one for guitar, one for bass. Having both a 1/2" open-end wrench and a 5/16" truss rod wrench means bridge and neck adjustments on American instruments are covered. Fold-out tools are securely housed, lowering the risk of loss during gigs or travel.

Precision Adjustment Tools for USA Guitars & Basses

With the right size tool on hand, you can keep setups smooth and safe. Inch-sized hex keys, a truss rod wrench, and an open-end wrench help eliminate stripped screws and guesswork during adjustment.

• Hex Keys: 3/16", 1/8", 7/64", 3/32", 5/64", 1/16", 1/20" — ideal for bridges, saddles, and hardware on US-made instruments
• Truss Rod Wrench: 5/16" — for precise neck relief adjustments
• Many players find the 1/2" open-end wrench particularly useful for fitting common US bridge nuts.

String Management & Quick Maintenance

String changes and on-the-fly repairs are much faster with this kit. The dual winders and integrated string cutter accommodate a variety of string gauges and tuning machines.

• Restring both guitar and bass efficiently using the dedicated winders
• String Cutter: built-in — slices through all common gauges
• The bridge pin puller is built right into the winder for removing acoustic bridge pins easily

Additional Essentials for Everyday Setups

For complete control, the MultiTool adds screwdrivers and a dual-scale ruler for setup measurements and minor repairs.

• Ruler: 50 mm / 2" — check string action or pickup height
• Flathead Screwdriver (PH1): included for adjustments
• Electronics and hardware adjustments are simplified with the Phillips Screwdriver (0.4 x 2.4).
