How to fill a nut slot properly

[CharlieMac]

I've r read about the old time players putting little pieces of dollar bills in the slots to raise the strings a tiny bit.
Now that's rich!

When shimming a nut from the bottom, what is the choice material to use for the shim?

If it's a cheap plastic nut it hardly matters what you use. Otherwise I prefer to match the material of the nut - bone to bone, Tusq to Tusq, etc. In a pinch I superglue the nut to a business card, trim to the nut when it's dry, then saturate the shim with CA. Makes a pretty hard shim that can be worked a bit if needed.

Brass nut. They last for years and years. If the slots eventually get worn too deep, a bit of silver solder fixes them up for another twenty five years or so of heavy playing.
