Trouble Getting in Tune

[JosephW]

First, I don't have this problem with any other guitars of mine, but I have this little Alvarez travel guitar that simply will not get in tune.

I can use a Snark or use an app to match tones, and no matter how perfect the match is, as soon as I make a chord, it's not right. Seems to affect the D string most often, but can happen on other strings as well.

When turning the tuning peg, which is very stiff, sometimes there is a creaking sound. Can't exactly locate its origin.

What steps should I take to run down the cause of this? I've checked the neck relief per frets.com and it seems ok. The strings are new and the proper guage. The guitar is a year old but only a month in my house. Humidity has been crazy lately, but ranges from 45-55%. But none of my other guitars is having a problem.

I don't expect much from this guy, it was a package deal and essentially free. But at least be tuneable.

Next step: make sure the nut slots are not binding? Graphite the slots? The tuning gears are sealed, but maybe a touch of lube around the post?
Sorry for the long post, but wanted to give as much info as possible.
Thanks.

Hey Joseph.

If you post this in the build and repair forum you will get a better response. I am sure someone there can help you out.

Oh, you're right! Sorry about that.

There's a few things that can cause that - nut height, frets, intonation etc.

Thank you.
