MusicNomad MN238 Heel Nut Truss Rod Wrench – truss rod adjustment wrench at the heel – 1 pc

MusicNomad MN238 is a double-ended tool for adjusting a slotted heel-end truss rod nut on guitars and basses. Its angled design (45° and 90°) enables precise neck relief adjustment without removing the neck or strings.

The MusicNomad MN238 Heel Nut Truss Rod Wrench is designed for quick, accurate truss rod adjustments on instruments with a slotted heel-end truss rod nut. It’s especially suited to Fender-style guitars and basses, helping you dial in neck relief efficiently for improved playability, intonation and setup stability.

It is primarily intended for Fender-type models such as Stratocaster, Telecaster, Esquire, Mustang, Jaguar, Jazzmaster and Precision Bass.

Thanks to two working angles – 45° and 90° – the wrench reaches tight spaces between the body and pickup with ease. You can adjust neck relief with the strings on and without removing the neck, significantly speeding up routine maintenance and professional setups. To access the nut, you may need to remove the pickguard.

Made from durable carbon steel and fitted with an ergonomic handle, it offers a comfortable grip and excellent control for small, precise turns—ideal for careful tightening or loosening during setup work.

Key features:

• Two working angles (45° and 90°): Innovative double-ended design for easy access to the slotted nut even in very tight spaces.
• Adjust with strings on: Speeds up action and neck relief adjustments without neck removal.
• Ergonomic handle: Custom handle provides a secure, comfortable grip and high precision for fine adjustments.
• Premium construction: High-strength carbon steel for long life and a precise fit in the nut slots.

Who it’s for / best use: Ideal for guitarists, bassists, techs and luthiers who regularly set up Fender-style instruments. Perfect for any playing style where low action and stable tuning matter—blues, rock, funk, pop, country, jazz and modern session work—because accurate neck relief is the foundation of a clean, comfortable setup.
