Safe Slot Nut Slot Set

Stop your file before the slot’s too deep!
Cutting string slots is delicate: if you cut one slot a little too low, you've blown the nut and have to start over.
Stack feeler gauges against the nut to set your slot depth. When the slotting saw touches the feeler gauges, you've hit your depth. The Safe Slot Nut Guard holds the feeler gauges tightly against the nut, and curved to the radius of your fingerboard. This leaves both hands free for filing. You're able to work faster without worrying about cutting too deep.
Holds multiple feeler gauges
Pulls gauges tight to match fretboard radius
Locks in place against the nut. No slipping!
Perfect string spacing without math
For good playing feel, don't use equal spaces between the strings. Wound strings are thicker, so they need more space than thinner treble strings. In fact, every string space needs to be a little different to feel right in the player's hand.
The Safe Slot's felt-padded caul adapts to most neck shapes, and any fingerboard width up to 2-1/16".
