do fretboard inlays have any effect on my performance?

the feel or sound?

if i scrape the string across the fret with an inlay does it change the feel?

the sound?

i wonder how different grid systems/inlay placements have shaped my perception

dots help achieve a mapping.

a grid.

and if it affects playing and placement, and thinking

it affects creativity.

the 3 5 7 9 12 inlay grid system seems arbitrary.

i have seen a guitar design that has only one inlay on the 2nd fret, and another on the 12th fret. that is so perplexing.

if i design a guitar — i might follow that approach.

some guitar necks have the dots on the sides

some (rick toone) have engraved dots that i can actually feel.
