Replacing the standard revstar nut with TUSQ

As a few people have now asked about replacing that pretty awful Urea nut that is fitted to the revstar range of guitars I thought it would be useful to post this info.

The only model of revstar that comes with a good quality TUSQ nut is the top of the range RSP20CR and as all the revstar range share the same nut dimensions it would make sense to order the part for the RSP20CR and fit it to whatever model guitar you own.

So these are the details you need:

TUSQ XL BT-6041-00 43mm(Bl)
Part Number: WU137900

In the UK this can be ordered from http://www.sontec.co.uk
Not sure if they ship abroad but always worth asking.

Also one of our forum visitors from Spain emailed me to ask about this and he was able to use the info above to order a replacement on Ebay https://ebay.es/usr/gtr-music at a cost of about 16 €, (19 US $) including taxes and postage.

Hope that helps someone?

Brilliant, the solution served on a plate. ((i))

This relatively easy upgrade should improve the sound and sustain.

Yeah I think it is definitely the first thing I would do if I had bought a revstar.

Many thanks for this info. I've got a lovely 620 in Brickburst. I've just done an ebay UK search and gtr-music are UK based (https://rover.ebay.com/rover/1/710-5348 ... olid=20008) I've just paid £10.99 for the BT-6041. I'll report back when it arrives.
Cheers

Not to be an ass, but the "silver plater" suggestion is as wrong as you can possibly get it.

The description for the https://www.coastmusiconline.com/Catalo ... BT-6041-00 clearly states "for Yamaha Pacifica". Pacificas have much narrower string spacing than Revstars.

You need to measure and you'll likely find something like:
Spacing E to E ~35mm
Length:- 43mm
Height: 8mm (from lowest to talles point)
Width: 5mm (distance from fretboard end to nut end towards the strings)

Which leads you to choose the closest match here:
http://www.graphtech.com/products/brand ... uitar-nuts

The closest pre-slotted chunk I could find is PT-6114-00:
http://www.graphtech.com/products/brand ... 1985ca160c

This is almost spot on (Length 43.03mm, Width 4.95mm, Height 9.07mm, E to e 34.77mm) except for its overall height, but it's very easy to remove ~1mm from the bottom or as much as needed.

Another approximate fit is PT-6643-00:
42.95mm 5.98mm 7.95mm 35.22mm

E to e is a bit wider (not a big problem) however it could be a little too shallow just under 8mm and you also likely need to shave off 1mm of its width, as it's close to 6mm as opposed to 5mm which is what the stock revstar nut measures.

So I'd go for PT-6114-00 and place it as it is, then see how the setup goes and shave off as much as needed from its bottom. It's the cleanest and safest preslotted option, in my opinion.

Tuning stability, too, since it's a self-lubricating TUSQ XL nut.

Hi guys. My first post, thought it might be helpful to others contemplating a nut change on their Revstar as I've just done my 502 to rectify tuning issues. Apologies for length of post

After measuring and checking dimensions I went for the Black Tusq PT-6114-00 as mentioned by apocapsile as the nearest equivalent. Worth noting that the dimensions quoted by apocapsile, which are the same as those quoted on the graphtec website, are not quite right. Don't worry though as it is a great fit! The dimensions as listed on the card the nut comes on and in the graphtec catalogue download are (mm) 43.31L, 4.95W, 8.43H with E to e of 34.90, slightly different to those quoted on the website. I think the graphtec website for this nut is the only one where it doesn't list the dimensions in inches as well as mm so think some data may have got mixed up. Anyway, the 2 UK sellers on eBay listed the correct dimensions as given above.


I measured my OEM nut at 35.6mm E to e (centre of grooves) so Tusq nut does put the strings ever so slightly closer together. See pictures attached. There was no discernible back to front movement in the slot and it's quite a snug fit. The slot needed a small bit of dressing to get rid of the nasty superglue that had been used. No overhang at the edges with the new nut, certainly nothing worth the mention so nothing to file. Heightwise it's almost perfect out of the box. I sanded it very lightly at the bottom to ensure it was flat and take of any little projections. When fitted the bottom of strings were around 0.5 to 0.6mm above 1st fret, I like them around 0.4mm or until there is the tiniest gap between string and first fret when fretted at the 3rd fret. This helps reduce sharp intonation issues at this end of the fretboard. It took very few strokes of the nut files to cut grooves down by 0.1 or 0.2 mm.

Here's the good news, no more tuning issues! With the OEM nut the unwound strings would tune in little stepwise pings which was hard to tune accurately and sometimes would ping sharp when you started playing, that's all gone, result!

I got mine in UK from guitarbitzmusicstore on eBay for £8.39, gtr-music on eBay also sell them for £10.99. Hope that helps.

Just a quick addendum, I've measured the Yamaha OEM nut and it comes in at 43.00L, 5.00W and 8.64H (at tallest point) with E to e of 35.6mm. As you can see the Tusq nut I used is 0.2mm shorter in height but in practice it seemed to put the strings at the same height as the OEM nut which I found a little high. I usually find I need to file down the grooves to lower them a fraction to improve intonation but you may be perfectly happy with the string height as it comes in which case it is a direct swap with OEM nut. Best wishes.

Excellent first post their Richard and a very warm welcome to the forum :clap: :clap: :clap:

Details like this are incredibly valuable to people looking to get rid of that really awful nut that Yamaha fitted to the revstar. Sometimes makes me quite angry that they thought it was ok to fit such a low quality component on these guitars. Charge a few quid extra if they must be please give us quality components all round!

Thanks again. (Y)

Thanks for the welcome Saul. Yes, it's hard to understand why Yamaha penny pinched here when a good quality nut is relatively inexpensive. It spoils what is otherwise a lovely guitar, anyway, relatively easy to fix though you shouldn't have to! I can go back to enjoying it now. :D All the best

Many thanks for an informative and practical post.
Just ordered two nuts from gtr music.
My own tip to improve the playability of the Revies is to carefully and lightly sand the back of the neck after taping top and bottom. Works for me - and still looks gorgeous after being played in. Photo to follow....

Thanks for the tip. I was thinking about doing that as the gloss finish on the neck is a bit sticky, was afraid I might spoil the look of the guitar though. Would love to see your pictures

Great guidance!
I've got a 620 and an 820 Revie. The existing action on the 620 which I bought on ebay is perfect for me, so I'll duplicate of it's nut dimension and depth of cuts.
You mentioned that the original nut was super-glued. Was this problem when you knocked it out?
