Solid wood moves with moisture. The goal isn’t perfection — it’s staying inside a band where glue joints, bridges, and frets stay happy. Think slow, steady changes instead of hero moves.

Chapter I

Numbers that work for most shops & homes

Aim for roughly 45–55% relative humidity if you can. If you’re in a dry season, a room humidifier beats stuffing dozens of soundhole sponges into every guitar you own.

Stability is a habit, not a single purchase.
  • Keep acoustics in the case when the HVAC is aggressive.
  • Check the case with a small hygrometer — the room reading lies sometimes.
  • If you see sharp fret ends, don’t panic — it’s often seasonal shrink.
