No, it's true, IME. Remember that you are hearing the entire room respond
to a guitar amp, not just the "mic's eye view" right in front of the
speaker. Room response is everything to the subjective perception of an
amp. Just as the crowd size will have an effect the humidity will have an
effect on the tone. Perhaps the paper will be a bit different with absorbed
moisture, but it seems to me as if that would take a lot of moisture. Highs
are more easily damped than lows, as the previous poster said.

Your recording example would be OK if you had mics all over the room, I
guess, but the ear is much more sensitive to changes than any recording can
be, and I'd be surprised if the difference "translated" in the recording all
that much.
