leeasam, MexicoMike and Puretone, Those are great responses.
I agree to look for mechanical reasons first. The truss rod is not meant for action adjustments, but if the neck isn't right,...the action won't be. In my case it was obvious the neck wasn't perfect. I've been a Carpenter for 35yrs. or so,... still have a "good" eye.
Sanding saddles or anything else obtrusive is not a good idea on a new guitar.
The most important factor for anyone that would under take a truss rod adjustment is,.... wood does not move fast, it takes time, overnight at least. I moved mine maybe 30 degrees, waited about an hour and measured, it moved in the right direction. I played/practiced and put her in the case humidified. In the morning i got it out and it had moved 1/32nd. It's now 5/64ths just what I like.
I guess the point I'm trying to make is if you undertake a mechanical adjustment, go SLOW, a little can go a long way.
If you don't understand what you're doing, take it to a good shop!!
Best, Rick
