A range of pre-designed multiscale fret slotting jigs for 6, 7, 8 string guitars & 4-string bass guitars. The supply includes a layout gauge to assist nut and bridge angle positioning. The layout gauge also features the geometry and relationships of the bass and treble scales to each other and reference to the centre line of the instrument. The jig is strong enough to be clamped in a bench vice for easier working.


The supply includes:

  • Multiscale Fretboard Slotting Template.
  • Multiscale Slotting Jig Base.
  • 2x Fret Slot Locators.
  • Multiscale Fretsaw (for depth see below).
  • 5x Fretsaw Blades.
  • Multiscale Layout Gauge.



The jig base has a ribbed top to help restrict movement of the fretboard.

The fretboard blank width should be trimmed for a snug fit inside the jig base side plates.

The multiscale fretboard template rests directly on top of the fretboard and is fastened in position via screws along the sides of the jig base.

The saw blade back is guided in the template slots and the tooth set passes through notches at the corners of the template. (See Photo 1).

A fret slot locator should be inserted after cutting the initial slot. It is recommended to use both slot locators and position these at opposite ends of the fretboard.



Fret slot depth is achieved when the fretsaw spine contacts the top surface of the template. The fretsaw supplied – 4.5mm depth – includes an allowance for the template thickness. 5 blades are included with the saw. Spare Blades can also be purchased from the webstore.



The Layout Gauge is an invaluable reference tool for the instrument build. The gauge features the geometry and relationships of the scales with reference to the centre line of the instrument as follows:

Nut Angle

Bridge Angle

Treble Scale Length

Bass Scale Length

Nut String Spacing (Overall)

Bridge String Spacing (Overall)



The multiscale jig base is 715mm long and will accommodate 78mm maximum fretboard width. The fixing screw positions are common permitting our standard bass and guitar scale templates to be fitted also. If purchasing standard templates for use with the jig, it is recommended to also purchase a 2.5mm depth fretsaw.



(Scales-Strings-Nut-Bridge-Level Fret)


















Additional templates are available for the jig.
