Bass Guitar Dual Notched Straight Edge 30"- 38" range.
The tool accurately checks the neck straightness & fretboard flatness independent of the frets.
It is suitable for any scale size that falls within the range quoted.
The notched straight edge tool is made from stainless steel and 100% inspected for accuracy. The edges have a high surface finish, lapped flat to within a total tolerance of 0.035mm (0.0015") over the tools length. The accuracy is checked on a calibrated (grade 000) precision granite inspection table - (table flatness quality inspection report 1.5 microns).
The tool has 18 notches and the design is based on checking the length of the fretboard that is capable of being deflected. The highest frets are omitted since these are well beyond the heel/neck join and are therefore not affected by truss rod adjustment or string tension.
A double dot mark for position reference is provided on the tool. The positioning on the neck will vary depending on the scale of the instrument i.e.:
The dots are nominally positioned at the 12th fret.
For shorter scales, the dots are placed at the 11th fret and for longer scales the dots are placed at the 13th fret.
A removable steady prevents the tool from toppling over, allowing it to remain safely positioned on the neck during setup and adjustments. (The steady can be used with or without strings fitted).
Universal design covers a wide range of scales.
Freestanding use with tool remaining in position, ensures easy observation of changes to neck when adjusting the truss rod.
Can be used for checking multiscale guitars.
