Hey everyone,

Guitar #1 has been in my hands for six months now and the more I play it the more I like it.  I think #2 and #3 are jealous, but I'll get over that.  One issue that has sprouted in #1 is an almost unruly upper harmonic ring at the beginning of each attack on strings 1 and 2. 

The bridge and bridge pins are EIR, bone saddle and nut.  Overall action is set fairly low, but there are no buzzing frets anywhere. 

I'd call it a tinny tone, but the overall tone of the instrument is anything but tin.  The ring is just as prevalent with fretted notes as it is with open strings. 

Could someone give me some troubleshooting advice on what to look for?

As always,
Thanks in advance for the advice,

Dave

If this just sprouted up sometimes it as simple as the tip of a string that passes through a tuning gear hole touching the next string. It can creat a overtone or a slight buzzing sound. I have seen this happen. That why I bend the tips up.

As Hesh said the tilt of the nut slot needs to be more than the angle of the string from the post to the nut. It does not have to be exactly half of the peghead angle, but half will guarantee you have no issues with the sting touching out before the edge of the nut.

Also the the apex or highest edge must be at your what ever point on the nut you use as your intonated zero on the scale.

Notice I did not say it had to be at the fretboard edge of the nut, because some use the nut to do fine intonation.

Doesn't that statement eliminate the nut as the cause?

I'd look at frets, saddle and/or having your string balls properly seated.

Sounds like it could be a flat saddle crest.
