Your guitar is alive –  you already knew that, so we're not telling you anything new. But are you aware of the fact that your guitar breathes? Especially during the cold months, heating air dries out your favourite instrument, resulting in cracks, damages to the paintwork, and expensive repairs. But too much dampness is also damaging: the wood can swell, causing the guitar to become deformed.
Your guitar feels best at an air humidity of 45 to 65 %. A hygrometer reliably shows you when action must be taken.
