String Spacing Nut Rule

To use the String Spacing Nut Rule start by marking the position of the two outside strings. These are usually spaced 2.5-3.5mm from the edge of the fingerboard depending on the type of guitar and player’s preference.

Once the outside two strings are marked find the correct place on the rule to have 5 spaces between them (5 spaces for a 6-string guitar, 3 spaces for a 4-string bass)

As the intervals decrease along the length of the rule it’s easy to find a spacing that works perfectly for any neck width. Once you find the correct placement mark the other string positions and slot the nut.
