Musiclily Pro Slotted Bone J Bass Nut With Curved Bottom for 4 String Jazz Bass, 39.5x3.2x4.8mm (Set of 2)

Worked well with a minimum of work to get it to fit and correct string height

Excellent product. Of course they must be custom fit to each bass, but it was simple and it sounds lovely.

It was maybe a hair too wide but works very well as replacement nut for a Monoprice Indio Jazz Bass. It slid in nicely, not too tight or loose. And the string heights were almost perfect. They provide the dimensions so ignore the reviews who buy a p-bass nut and complain it doesn't fit their jazz bass. Also nice it comes in two in case you mess up filing.

Fit my '76 Fender Musicmaster bass very well. Filed off a bit on each end to match the neck width & deepen the string slots to match the original. Its a perfect fit in the neck slot so no altererations were needed there.

The nuts seem to be well made although, I do not have the bass that fits these. It's my bad. Luckily I rebuild basses and guitars so eventually they will be put to good use. By measurement it seemed to be the right length but, after removing my original nut I found mine to be a flat bottom. Oh well they will be put to good use when a J bass comes into get repaired.

My new bass has a nut which was cut too low from the factory. These new nuts provided are wider and not aligning with proper JB string spacing. I wanted this to work as a drop-in nut replacement. Ended up shimming the existing nut with a paper business card and wood glue. I will keep these for possible use on a P or other in the future.

Seems like a nicely made nut but the slots are too wide for my squier 70’s classic vibe jazz bass. Thought I measured correctly..but live and learn!

Worked perfect for my Squier Classic Vibe Mustang bass
