Guitar Notched Edges For Every Scale
Updated: Aug 21
“I received the notched straight edge today and just wanted to let you know I am very happy with it. The quality of the tool is outstanding. The integrity in the work you do is evident in the workmanship of your products. In a world where cheap poor quality tools are abundant, tool makers such as yourself are providing guitar makers/repairers high quality tools to in turn do quality work. Thank you”.

MULTIPLE SCALES THROUGH INNOVATIVE TOOL DESIGN
Our guitar notched edge tools are designed to assess the length of the fretboard that can be deflected. The highest frets are excluded, since these are past the neck heel, where the fretboard is unlikely to be affected by truss rod adjustments.
This approach minimises the number of notches required, and the notch spacing design enables the tool to be used for any guitar scale, that falls within the specified tool range.
SMALL SCALE GUITAR NOTCHED EDGE
20-24" (Typically Gretsch, Jackson, Fender Mustang / Jaguar)
The largest notch on the tool is placed over the 1st or 2nd fret depending on the particular scale of the instrument. The tool is suitable for zero fret Instruments.

UNIVERSAL NOTCHED EDGE RANGE 24"-38"
TOOL #1) Guitar/Baritone 24" to 30" - (610mm to 762mm).
TOOL #2) Baritone/Bass 27" to 34" - (685mm to 864mm).
TOOL #3) Bass 30" to 38" - (762mm to 965mm).

MULTIPLE SCALES CATERED FOR ON A SINGLE TOOL
Example: Tool #1
This tool is compatible with the following popular guitar scales: 24", 24.5", 24.5625", 24.625", 24.75", 24.84", 24.9", 25.0", 25.34", 25.4", 25.5", 26", 26.25", 26.5", 27", and baritone scales up to 30", as well as metric scales from 630mm, 635mm, 640mm, 645mm, 650mm, 660mm, and 670mm up to 762mm.
POSITIONING ON THE GUITAR NECK
The positioning of the tool on the guitar neck will depend on the scale of the instrument.
The largest notch is placed over the 1st or 2nd fret depending on the particular scale of the instrument. The tool skips over the nut for the shortest scale - see note reference 'Guitars With Zero Fret' below.
Small double dot holes for position reference are provided. (The larger holes are for attaching the steady - see note below).
The tool is placed with the dots at the 11th fret for shorter scales and for longer scales the dots are placed at the 13th fret.
NOTE - GUITARS WITH ZERO FRET
For shorter scales the universal tool bridges over the nut and may not be suitable for guitars that feature a zero fret due to the extended nut position on the instrument. This applies to the smallest scale on the tool. If in doubt, please contact us with your requirement so that we can confirm suitability of the tool.
MULTISCALE GUITARS
Multiscale guitars with bass and treble scales within range specified can also be checked.
PRECISION IN-HOUSE MANUFACTURING
The notched straight edges are machined in-house using specialised carbide tooling. The edges are finished with ultra fine grit abrasive over a precision surface table.
ADDITIONAL FEATURE
STEADY FOOT – The tools feature a detachable steady designed to prevent tipping, ensuring the notched edge stays stable on the neck during setup and adjustments. The steady will find its own resting height, and should be loosely secured when placing the notched edge on the neck, then tightened with the single screw after the notched edge has contacted the fretboard. The steady has sufficient height travel to enable it to be utilised whether or not strings are fitted.
