What if my Martin has been stored in a dry environment? Low humidity seems to occur more often than excessive humidity. As your guitar dries, the wood actually shrinks. This results in the top lowering and the strings come with it. All of this stress results in the wood cracking. To solve this problem you should invest in a humidifier. Be sure to also get a hygrometer to measure how much humidity you bring into the air. Back to Top
What happens to my Martin at 60% humidity? At 60% relative humidity or above symptoms may include tarnished frets and strings, corrosion to nickel, chrome or gold plating on tuning machines, swelling of the top, high action and loose braces and bridges. Back to Top
What happens to my Martin at 30% humidity? At 30% relative humidity you may see cracks in your guitar. Even if you do not see a crack in the guitar, it has still lost moisture and the top has begun to sink. To make your guitar playable you may need a higher saddle. Back to Top
