I just ordered my first electric guitar

A roller nut because its a smooth rolling piece will allow for slippage back and then return to a zero point for the string at the nut. Hence increased tuning stability. This was before the locking nut. Why this and the later LRS roller nut never became mainstream is beyond me. I think it's far more effective than a locking nut.

I think this goes for saddles in the bridge as well, why not rollers?
- I used Schaller in a guitar as I remember

I payed more attention to nut since Bukovac mention it so often being the main reason for tuning instability. So for 3+3 tuners I make more of V shape to minimize amount of wall that string rest on sideways. The standard straight slot seems utterly wrong as an idea.

Also bought something to try other than graphite scrapings in nut slot
- Gewa Teflon Sattelpulver
- MusicNomad MusicNomad TUNE-IT (MN106) - String Instrument Lub
But have not tried it yet.

But over all I like the idea of fret zero, why a nut at all?
- you need to guide sideways, but to rest on?
- you have all these materials, bone, tusq and what not

Always like the sound with capo, and fret zero might be part of resting on solid metal?
- more solid contact with guitar neck it seems to me

Always find something to nerd around with. That's me...

Thanks for that. I'd forgotten all about zero fret though it did capture my imagination back in the 70's. I did have roller saddles on a guitar in the distant past. I've forgotten which guitar having had many through the years.

I do like the idea of cam rollers for trem systems. Most notably the Ric Toone replacement tremolo

A good deal with the whole Hendix thing was about slippage and unequal return at the nut. The string would slip back and not return.
Wilkinson resolve all this with a roller nut. A roller nut because its a smooth rolling piece will allow for slippage back and then return to a zero point for the string at the nut.

For me the main purpose of a locking nut was to prevent the strings from sliding off the nut entirely during extreme dive bombs. Since I don't do those anymore I have removed the nut locks from my Ibanez 540R. In spite of the Floyd Rose this guitar stays in tune remarkably well.
