Pre-slotted, oil-treated vintage cow bone nut for acoustic guitars. Regarding the sound, it depends on personal preference, but the oil effect significantly reduces wear from the strings. Tuning becomes more stable. Size: Nut: Length approx. 43 mm, Height approx. 9 mm, Width approx. 6 mm (LP compatible) Please check the size. E to E (distance between 1st and 6th strings) approx. 35 mm Warning! A new nut doesn't always fit a guitar just by putting it on. Some adjustments are needed to fit the guitar and make it easy to play, while checking the string height. Basically, you can sand it with sandpaper, but please search online for how to do it. I also have many other guitar maintenance supplies for sale. Thank you!
