StewMac Safe Slot Nut Guard

About This Item

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. StewMac's own Don MacRostie devised the Safe Slot™ to make accurate nut slotting fast and fumble-free. He shows us how it's done in the video!

A trick the pros use:
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.

This set includes tapered wedges for both electric and acoustic guitars to mark out your trim line and a slim version of our String Spacing Rule to show where to put your string slots. Slide it into the Safe Slot, same as a feeler gauge, and see exactly where each string belongs. No measuring, dividing or calculating. Replace the rule with your feeler gauges and you're ready to cut nut slots. Thanks to luthier Ron Baran for the idea of adding this slim spacing rule to the set.

The Safe Slot's felt-padded caul adapts to most neck shapes, and any fingerboard width up to 2-1/16".

    Safe Slot Nut Guard Complete Set includes:
  • Safe Slot Nut Guard
  • Electric and acoustic wedges for trimming the nut top
  • String Spacing Rule to locate nut slots
  • Feeler Gauge Set (size 6" x 1/2")

Safe Slot Nut Guard

By

Verified Buyer


Don't do much "from scratch" nut installations usually relying on pre-slotted installations. However thought I should have this on hand "just-in-case". Did notice the felt pad seems ill-fitted (not centred and crooked). Should work OK, if not I'll just cut it off & re-install it properly. Simply poor quality control. Also the printed material supplied with the kit leaves a lot to be desired (very sketchy). I assume your full video would be a recommended purchase.

Works great, instructions included leave a bit to be desired, but the online video compensates for this.

Great time saver!

It removes the guess work for spacing, shape, and depth. My first job was replacing a nut on a 70s Cortez Les Paul copy. I bought an Epiphone replacement nut, which is a 12" radius but the LP copy has a 9.5" radius. Instead of file, check on the guitar, file, check, file... I was able to get all the measurements and get ready for the final finishing work in about 30 minutes instead of a couple of hours.

Safe Slot Nut Guard

This little tool allows me to get aggressive when making nut slots and eliminates the concern about cutting just a little bit too deep. It also eliminates the constant checking especially when getting close to the proper string/fret gap. A great time saver.

Game Changer

By

Verified Buyer


This tool gives a beginning guitar tech “wanna be” the ability to make a decent bone nut from a blank. Instead of constant paranoia about a slot that is too low, you can work on creating properly shaped slots with a clear front takeoff point and ramp. The screw is definitely finicky which is the only apparent defect I can find. Overall a great tool created by a Lutherie genius.

Useless for a guitar with a volute

By

Verified Buyer


2 of my electrics have a volute in their neck, which makes this tool useless to fix the feeler gauges flush on the fretboard. I didn't read any caution about this detail on the item description. I should have gone with the nut slotting gauge instead

Quick accurate setup.

Should have had this tool years ago. The time I save and accurately doing it right the first time paid for the kit in three setups. Outstanding and a must have.

LOVE -  But one note of warning!

By

Verified Buyer


I seriously love this thing. But be careful not to over-tighten the neck caul when bending feeler gauges to match neck radius. Over-tightening (and it's 'very' easy to do) will cause a hump at the middle and completely negate the tool's purpose. Trust me, it's very easy to make this mistake without realizing it.
