Fret Slot Depth Gauge

Dan Erlewine demos "a little tool with a big job". Before you try to put frets in your guitar, make sure the slots are deep enough.

Off topic: anyone knows the brand of the shirt of Dan?

A cardstock gauge would get ruined quite fast since the slot is often not clean on a guitar where the fret has just been pulled off, and you will need to make new ones often, wasting a lot of time. Maybe 5$ is a lot of money for this tiny metal plate, but you buy this once and it will last forever. Or at least this is my opinion after owning it since some years. :)

You could easily just print one of these off on some thin cardstock.
