Sharp notes on 1st and 2nd fret
« on: November 09, 2009, 09:59:21 AM »
Hi guys,
after filing the nut with the correct files on my 95 Deluxe (copying the height between teh strings and the 1st fret from the Mojo), I noticed that the notea are 15-20 cents sharp on the first fret, around 10 on the 2nd, and from the 3rd and on everything comes back to normal.
What can it be?

I was thinking about:
- nut: may the slots are too deep or not deep enough, so that the string arrives to the first frets with a wrong angle when pressed down to the fretboard, therefore not having the right tension and playing slightly sharp?
- truss rod: (unlikely) may the neck present a little bow and make the first fret sound slightly out of tune?
- other serious things like neck warping or gone frets.. and this would mean something VERY bad

Thank you for your help

Can you post a close up side view of your new nut? In focus.

Here are the pics (link below):

I've taken them from different POVs, and on both sides of the neck (first bass, then treble side).
If you need more from different angles, just ask.
Thanks! :)

Oh.... what's wrong with zip files?
Anyway, no problem, I uploaded the images on Imageshack. They're too big to be shown here and they would mess up the post. An external link is more elegant (engineer's tip!), a tehy are managed as an user-friendly photoalbum ;)

Thnk you 908ssp and Simonlock for your precious help

The bottom of the nut isn't flat to the head stock. The angle of the bottom on the nuts I have seen had to be cut to fit not sure if yours is like that. Not getting the angle right moves the edge where the strings exist the nut back changing the intonation making the string longer which throws off the pitch. The strings look to be high especially the g and d strings. I check the height by fretting at the first fret and the gap above the 2nd fret is what I shoot for. The higher the string the farther it stretches again rising the pitch.

Ok I cut them better, I also tightened the truss rod alittlem ore.
Now I'll wait for a few days, and then let you know if it has improved
