Warwick Just A Nut III Brass 4str/38,5

I fitted this to my 2007 GPS Corvette that already had a Tedur JAN-III on it. The fitting was easy enough - I just had to make sure the seat was clear of any existing glue and that the part of the headstock that the base seats on was exactly a right-angle to the top end of the fretboard, so be prepared to do a little work if yours needs doing this as well and only do if you're confident doing this kind of work. You don't want to make a mess of it.

Also, when fitting, be very, VERY sparing with the amount of glue you put on the base of the nut. I put on a tiny amount, yet there was enough for some surplus to come out around the edges. Also be aware that loctite superglue sets FAST. Make sure your nut is in exactly the right place before setting it down, otherwise you'll have a mess on your hands!

Once on, I noticed an immediate difference to the Tedur JAN in that the top part of the nut doesn't sit parallel to the base, it rocks forwards or backwards until the strings sit completely parallel in the grooves. In my case this meant that the top part of the JAN rocked forward towards the fretboard and sat at about a 5-10 angle to the base. I initially thought this was a fault and sent some pictures to Warwick, who were quick to respond and let me know it was normal. Since then, I've seen Andy Irvine playing with his brass JAN-III and his is the same. Phew!

Anyway, after all that, it is on and... the brass JAN-III is just ridiculously good. Like all JAN's it means you get another level of adjustability with your nut, all without filing or permanent change. However, what is really noticeable and the main benefit is the sustain it gives. A open string will just ring for ages and sounds so open and clear, really complimenting that Warwick sound and further brings out that low end growl. The way it rings out is piano-esque in it's nature. Plus it matches my bell-brass frets and looks the business.

It is expensive, but if you love your Warwick, it is a worthwhile investment.

The best nut in existence!
Bell brass is absolutely the best material for a nut for a crisp and solid sound, extremely recommended for death metal.
Warwick shows that the slot takes strings up to 0.114, and included instructions to use a 3.1mm file to easily fit up to 0.121, as i did and it worked like a charm.
I used it to upgrade my BTB bass, along with warwick brass frets,
it's expensive but definitely worth the money. Brass is eternal.

Pros - crisp sound, amazing resonance; Easy install; height adjustment screws make action adjustments easy!
Cons - price; Much more expensive than ABM brass nuts.

bought this for my 2005 corvette standard and it looks the dogs!
it changed the sound also from having a very clicky top end to more mid sounding.
really easy to fit youself, remove the old one with a sharp Stanley blade or craft knife
(be carefull not to mark one of the best basses in the world please!) clean of any residue from the previous glue with you blade/knife then use just two dots of superglue and I mean two dots as the force of the strings and the fact that the surface being smooth will transfer the glue into a thin layer and will surfice !!! once positioned carfully just two strings, two center or two outer strings can be put into place to keep it down and held in position.
once dry, tune your bass to your pitch and adjust the nut up or don depending on your fret board to the point were your string just stop ringing when open. if your fretboard is in good condition there is no reason why this should'nt be straight forward...... mmmmm niiiice.
