JE042W Music Man Compensated Nut – StingRay 4 – Black – compensated nut – 1 pc

JE042W is the part code for an original replacement compensated nut blank from Ernie Ball Music Man, designed for Ernie Ball Music Man bass guitars. This specific part is finished in black.

This JE042W Ernie Ball Music Man compensated nut blank is an original replacement part designed to improve tuning accuracy and intonation in the lower positions of the fingerboard. Made for specific post-2005 Music Man 4‑string basses, it features the correct compensated shape and seating, and comes in a sleek black finish. As a nut blank, it is intended for precise final fitting by a technician to match your preferred string gauge and action.

Key features & compatibility:

• Purpose: Designed for Ernie Ball Music Man 4‑string basses with a 1-5/8" nut width (approx. 41.3 mm).
• Compatible models: Fits instruments made after 2005, such as Bongo 4, Cutlass 4 and Reflex 4.
• Compensated design: Helps significantly improve intonation and tuning accuracy in the first positions.
• Colour: Black.

Who it’s for / best use:

Ideal for Music Man bass players and techs who want factory-correct replacement hardware and more accurate intonation near the nut—great for precise playing, studio work, and styles where clean pitch matters (funk, pop, rock, modern gospel, and tight fingerstyle or slap playing).

Important installation notes:

• Requires fitting: This is a blank (semi-finished part). The string slots are only pre-formed and must be final-filed with proper nut files after installation to suit your string gauge and setup.
• Specific shape: Music Man compensated nuts were introduced from 2005 and use a specific seating. They do not fit older models with a standard straight nut slot.
• Not recommended for other brands: The manufacturer does not recommend installing it on other bass brands or on Sterling by Music Man licensed models, where major cutting/filing would be required for correct fit.
