New Strings New Nut?

[tensen]

How much variance between strings are reasonable to go before you change your nut or file the original?

I'm still in the middle of trying strings to know what I like. I'd like to know how close the strings should be that I'm comparing without having to change more of my instrument in the process.

A regular nut should be able to accommodate all standard string sets. No need to do anything.

I have never had to change the nut on my tenors. I have tried different brands and I have tried wound and unwound strings, high G and low G, baritone strings, and concert strings. The nut works with them all.

In the event of a string being too tight in a slot there's a good chance it'll jam and snap, so the slot needs to be wide enough. Some graphite (from a pencil "lead") or other dry lubricant may help here.
If the slot is too wide there's a risk of the string rattling/buzzing.
In the first instance, file the slot wider.
In the second instance, fill the existing slot (baking powder and a drop of superglue is a tried and tested solution) then re-cut to suit. This also works if one's been a little over-enthusiastic when trying to lower the action

I have noticed intonation issues when trying out a new set of strings with different diameters than the original.
