Australiaâs tallest trees can be found in the south-west of Western Australia in the Valley of the Giants. Giant tuart, karri, and rich red jarrah which live for up to 500 years can be found here.
Feeler gauge set. A feeler gauge is a tool used to measure gap widths. Feeler gauges are mostly used in engineering to measure the clearance between two parts. They consist of a number of small lengths of steel of different thicknesses with measurements marked on each piece.
With your free hand, use the feeler gauge to measure the gap between the bottom of the string and the top of the eighth fret (the fret wire itself, not the fingerboard), which is where the curvature should be deepest. Repeat this process on the low E string (for both guitars and bass guitars).
