Common Questions

Is this nut compatible with a standard 4-string bass guitar?
Yes, this brass nut is designed for 4-string basses with a width of 38 mm. It is not suitable for 5+ string basses or guitars.
What material is this nut made of, and does it require special care?
It is made of brass, precision CNC machined. Brass is durable and corrosion-resistant; no special care is needed beyond occasional cleaning.
What is included in the package?
The listing includes one 38 mm adjustable height roller nut. Additional hardware such as screws or tools is not specified as included.
Can I use this nut on a bass with a fixed-height nut or different string spacing?
This nut is designed for adjustable height (7 mm) at the nut and is not intended for fixed-height preferences. It is made for standard 4-string spacing; verify your string spacing before purchase.
How long does shipping take, and are there any restrictions?
The product ships from China; typical delivery is 7-30 days depending on the shipping tier. Checkout requires human approval, which may add a short delay.
