Profile a new top nut, choose the optimum string spacing and set the nut slot action with precise accuracy. A repeatable luthier tool system that simplifies guitar nut making, string spacing - and improves action & intonation.
Please see the Nut Replacement Video for a short demo of the tools application.
The string spacing is compensated by a proportional increase between adjacent strings from treble to bass.
For 7.25" / 9.5" / 10" / 12" / 14" / 16" / 17" / 20" & Flat Fretboards.

COMPENSATED STRING SPACING:
With uniform/equal string spacing, the space in between the strings decreases towards the bass side. This can be quite significant for adjacent roundwound and heavy gauge strings.
With compensated spacing, the string spacing is incrementally increased so that the space in-between adjacent strings is similar across the fretboard.
To get the best spacing for your guitar, we recommend setting the overall string spacing to the maximum that the guitar will allow. A small increase without encroaching on the fret chamfers is often achievable.
This system is accurate and repeatable. A specially made string position marker and guiding template ensure the strings are precisely positioned along the nut. This avoids any discrepancies with individual hand marking out of each slot as all of the slots are cut in the same setting.
The most unique feature of this tool is its comparison of the instrument. The jig is set up directly from the guitar. Different string spacings can be easily experimented with and fretboard offcuts make ideal test pieces for practice nuts.
Should you need to do so, a precise re-make/copy of the nut is simple & quick with the jig already setup for the guitar.
GUITAR NUT & SADDLE VICE (Included)
A feature of the vice is its precise comparison of the fretboard nut slot depth. This allows nut shaping, string spacing and nut filing to be accurately performed off the instrument.
The comparison is achieved by a simple arrangement using two sliding plates that are used to gauge the depth of the nut slot relative to the top of the fretboard (similar to using a vernier depth gauge). After gauging, the plates are then locked together creating a datum for the nut to sit on.
The vice body has two location pins for locating the jaw. The top of the vice jaws simulate the radius of the fretboard and provides a reference for the nut height / protrusion above the fretboard.
The setup allows the nut to be removed and easily replaced in exactly the same position in the vice every time – in between any checks necessary on the guitar. The nut is always seated on its underside (datum) and there is no fiddling to adjust the height in the vice. This is beneficial as the nut may be quite small in height with only a small area to clamp against.
The nut seating plate has two different ends which can be easily swapped around - a flat end for standard nuts and a curved end for fender style curved bottom nuts.
The jig is designed for use in a bench vice for comfortable working.

“I want to compliment you on the guitar nut replacement & string spacing jig. I used it to make a new nut for a Fender Jazz Bass project. The quality of the tool and it’s utility is brilliantly conceived. Your tool will be my favorite whenever making or replacing nuts”. Jeff B., Massachusetts, USA.
“Amazing product, real quality and so much for the price. You cannot go wrong”. L.S., Worcestershire, UK.
“Just wanted to thank you personally!. The price is totally amazing for this fantastic tool. Wow. Impressed!. I will be buying a few other items from you soon”. R. Z., USA.
"Hello, I just wanted to shoot you a message and tell you how amazed I am by the product. I own a vintage repair shop and can cut a "good" nut with my eyes closed. This product allows me to do it faster and more accurate even than using calipers. GREAT PRODUCT!. I don't know how long it took to produce this entire set up but let me say thank you for your time and effort" B.L. , USA.
