I flew to buffalo before christmas with one of my axis. it was fine there, no problems, then when I came back the strings were flat against the neck. I prefer extremly low action because I have arthritis pretty bad in my wrists and knuckles, but that was a remarkable change. the first axis I got has only had to be set up once, so I've been extremly fortunate. generally, EBMM's necks are stable enough that for you to be having intonation problems may denote you needing a setup. something that happened with my peavey wolfgang (go ahead, laugh) this winter was the frets popping out of their seats. I've found the wolf's neck to be stable, but not as good as the axis, so it didn't surprise me that the ceck contracted and expended enough to actuallly knock the frets about. it took 2 rounds of fretwork before ALL the frets were back to normal. the oddest thing was that once the lower register was cleaned up, all of a sudden the higher frets started going sharp. what I was told had happend was slight changes in the wood (plus the frankly not too great factory fretwork) had distorted the frets profile enough that they had to be leveled and crowned. I've heard this same thing happened to 2 other peole in the last couple of winters.
