Re: Do you find guitars temperamental?
I've got one guitar that needs daily truss rod adjustments, and that started within a week of it getting here. The neck flexes backwards, causing the strings to increase in pitch. One day I'm in E standard, the next it's up a semi-tone, and all it does is hang on an interior wall next to 6 others that have no trouble. Playability remains the same, it's just the wood bending back.
That's a physical ailment of the guitar, to be sure.
But there are guitars that are temperamental, as Ace said. I've got 4 of the same model, from 4 different build batches, and all 4 feel identical. I had a 5th one that I just could not get along with. Same model, and no measurable physical difference (i.e. crooked nut, bad frets, neck profile variance, etc). It sounded fine, but there was something about the way the neck felt in my hand. I compared it to my others, swapping from one to the other, just to see if it was me, but it was the guitar.
Sold it to a buddy after almost 2 months of trying to work with it, and you couldn't get it away from him if you tried. Maybe if he played my others, he'd feel the same way, maybe not. Sometimes a guitar wants a different owner. I know it sounds hokey, but there's no logical explanation for some things.
