Are you in Australia? Where?
I had to have a neck reset on an acoustic guitar due to humidity last year, and since then I've been monitoring humidity in my home & the levels are frightening!

I have bought a de-humidifier to attend to the excessive levels & thankfully it keeps the acoustic neck in top shape.
But when I took it to Melbourne for repairs in 2013, the change in humidity was dramatic (I live just north of Sydney in NSW) & the neck was nearly normal again. The change in the neck's posture made me look a goose to the repairer, but luckily he understood that in other regions, the humidity is much higher.
Seems Melbourne is dry but Sydney & Brisbane humid. Adelaide & Perth - BONE DRY! And I guess you wouldn't even consider owning an expensive acoustic in tropical areas like Townsville & Darwin. :dontknow:
