I know what the signs are in acoustic guitars, but other that necks shrinking side to side and frets starting to stick out, and lacquer starting to check, what are the other things that happen that a lay guitarists can easily see? Thanks so much folks...
Obviously neck relief will change when the neck loses a bit of humidity and its a half a tweak here or there of the truss rod from season to season where we are. You got the fret ends.
Other than that I cannot cite anything that matters happening as a result of a reduced humidity environment wrt electric guitars.
Temperature changes tend to do in lacquer finishes, and increase humidity corrodes nickel silver frets and hardware/switch contacts bt that's another question.
All screws in the wood needs to be tighten.
Razor fret is the most obvious, but a few other things can happen...
Hope that helps!
