Musiclily Pro 43x5x9mm Flat Bottom Slotted Bone Nut for 6 String YA Style A Series and FG Series Acoustic Guitar (Set of 2)

These mention the Yamaha A and FG Series in terms of fit, but of course you can make them work on a wide variety of guitars--just take some measurements of your current nut. The slots are nicely cut for normal action, and you'll save yourself some time and money not having to shape your own!

Musiclily makes good quality parts, and I’ve always been very pleased with their products. These bone acoustic nuts are just as well-made as I expected. They’re finished very nicely, and the measurements are just as described in the listing. The slots are pre-filed, and everything looks bang on. You even get a complimentary pick included in the bag.I ordered the unbleached, and it has a very pleasant cream colour that would be perfect on a vintage instrument.At $14.73 ($7.37 each) they’re a tad pricier than some others on Amazon, but I really think the quality level is worth it. It never hurts to shop around a little, but I’d definitely recommend these.4.5 stars

I'm upgrading my guitar's plastic nut with a Buffalo bone nut, which fits perfectly on my Ovation guitar. This bone nut is strikingly white, enhances the aesthetic appeal, and is expected to deliver superior sound quality compared to the plastic version. As I’ve started crafting a few guitars, having an additional nut will certainly be beneficial.Replacing the nut is a straightforward task. In some guitars, the nut might be secured in a slot that requires careful tapping from the side to remove, but on my Ovation, it sits just behind the fretboard. To ensure a clean removal, it's important to score around the nut with an exacto knife to prevent chipping the wood.To take out the old nut, use a small block of wood placed across the frets and gently tap it with a hammer. Once the old nut is out and the new one is sized correctly, you can string up the guitar and tune it to check for proper setup. After that, loosen the strings and apply just a couple of drops of super glue to secure the new nut in place, allowing for easy replacement in the future if needed.

Mine is not an FG, but the fit (overall width) and the gap between strings seem okay.I haven't replaced the OEM part yet.This is MX3589UN-2. The finish looks good.We get two NUTS plus a fairly thick plectrum in the bag. Good value.
