Truss Rod Adjustment = Intonation?

[Raz]

I just read an article, and it stated that ...well heck here the article will explain it better:

If you change the string gauge you are using you will need to reset the intonation. Heavier gauge strings put more stress on the neck while lighter strings cause a reduced stress on the neck. Any time you adjust your truss rod you will need to adjust your intonation. Any changes in the neck will cause a shortening or lengthening of the string causing the intonation to go crazy on you.

Is this correct? Mr. Setup man to the stars, do you have an opinion?

That depends, It could change it it could leave it as it was. Every time you do make an adjustment, check it, you may not need to adjust it, theory says you will, but my experience has been you wont always need to.

I agree with warg....Change the strings, then check it out. If you go from 9's to 10's you probably won't need to do much, if anything. The strings will be a bit higher off the fretboard because the strings are thicker and will sit higher on the saddles. There is not a whole lot more tension with 10's but if your guitar is a trem you may need to tighten up the trem claw a bit. I am not a fan of the "use the truss rod to adjust string height" theory. Adjust the truss rod so you have very slight relief, then adjust the saddles. You want the neck as flat as possible without buzzing.

Good Luck!
