The supply includes:
- Multiscale Fretboard Template.
- Interchangeable Multiscale Slotting Jig Base.

NEW FEATURE-MULTISCALE GEOMETRY LAYOUT GAUGE:
The gauge is made from stainless steel and provides all geometries and relationships with reference to the centre line of the instrument as follows:
Treble Scale Length
Bass Scale Length
Nut String Spacing (Overall)
Bridge String Spacing (Overall)
The Layout Gauge is an invaluable reference tool for the instrument build.
MULTI-SCALE JIG OVERVIEW
The multiscale fretboard template is a specially designed channel shaped jig which rests directly on top of the fretboard and is fastened in position via screws along the sides of the jig base.
During sawing, the blade is guided in close fitting parallel slots and the saw teeth pass through notches at the sides of the template.
Fret slot depth is achieved when the blade back contacts the top surface of the template. (The fretsaw supplied – 4.0mm depth – includes an allowance for the template thickness).
The fixing screw slots enable height adjustment for different board thicknesses.
For reference, the template has fretboard centreline marks at each end.
The jig is sturdy and can be solidly clamped in a bench vice for stability.
The jig base also accepts our standard slotting jig templates for conventional Short Scale, Long Scale, Baritone and Bass Scales.
JIG SETUP / FRETBOARD PREP
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.
If there is excess length on the board then this can be utilised for clamping over the top of the template (at the end portions of the jig only - see photo above).
CUSTOM MULTISCALE JIGS & PACKAGES
Custom multiscale jigs and packages can be made to order.
Shipping for custom orders and multiple jig packages is approx 5-6 weeks from receipt of your requirements.
The following details for each multiscale will need to be confirmed prior to ordering.
'A' Overall Nut String Spacing
'B' Overall Bridge String Spacing
'C' Treble Scale
'D' Bass Scale
'E' Perpendicular Fret Position
'F' Number of Strings
Please see the diagram for clarification of these requirements.
JIG BASE DIMENSIONS
The multiscale jig base is 715mm long and will accommodate 78mm maximum fretboard width. The fixing screw positions are common permitting our standard bass scale, guitar scale & small scale templates to be fitted also.
*SPECIALIST MULTI-SCALE BRIDGE SUPPLIERS
Multiscale Bridges are available from specialist suppliers and these can offer a convenient option/solution for your bridge requirement. We recommend visiting Hipshot Products. They also have an excellent and easy to use Bridge Angle Calculator. Links are provided below.
Q. Can the jig be utilised for standard bridges where overall string spacings may be different to the specification.?
A. Yes indeed. If the overall string spacing on the bridge differs, then this can be accommodated on the instrument by adjusting the overall nut spacing with the same % factor (not measurement). This will ensure that strings still intersect all frets at correct theoretical points.
Q. Can the jig be used for different numbers of strings?.
A. Yes, similar answer as above. Any adjustments made to the overall bridge spacing must be made pro rata (%) to the nut. (The scale lengths for bass and treble will change slightly - this is dependant on the amount of change in string spacing).
