The Revstar nut - clearing up the confusion about Urea

Unread post by Saul » Mon Apr 15, 2019 10:20 am

As most of us know, Yamaha have been using a material called 'urea' for many of the nuts fitted to their guitars of late. This is especially true of the revstar range only one of which uses a different material 'TUSQ'.

Problem is if you Google urea it will tell you it is "a colourless crystalline compound which is the main nitrogenous breakdown product of protein metabolism in mammals and is excreted in urine" which is obviously not something most of us would want anywhere near a guitar!

However what Yamaha actually do is use synthetic urea which is a combo of synthetic ammonia and carbon dioxide.

Personally I think they should have used bone or TUSQ across the range but anyway, at least it is not what people were thinking it was :)

Perhaps the word Synthetic should be used in front of Urea . That way no one will think Yamaha are taking the ---s .

Ha ha, yes indeed Les (Y)

I really don't know why they would use urea anyway. It is not as though there are no great alternatives available. They used TUSQ on the RSP20CR and I personally think they should have used it on the whole range but hey it's 'Yamaha' and they have their own very quirky way of doing things ;)

My 2017 Stratocaster nut is described as synthetic bone, which sounds much nicer than saying its made from old recycled milk cartons or whatever, may even be Urea .

..or they could use 'NuBone' which is another of Graphtec's synthetic products. Why do Yamaha keep using Urea :?: :think:

Yes Fender have used the term synthetic bone for many many years it isn't a better nut but as you say it sounds better

I'm just wondering what properties a Urea nut has that makes it a preferred choice for Yamaha? Only thing I can think of is they produce these themselves so it keeps costs down?
