You just brought home your new baby, a beautiful, shiny acoustic guitar. All the reviews raved about its tune. You are so ready to jam. But one day you notice some dramatic changes in playing and tune. The frets are starting to buzz

What’s going on?

Your guitar most likely needs a humidifier. While there are tons of extras for guitars, a guitar humidifier is not optional. That is why we’ve compiled best guitar humidifier list to take the guesswork out of finding the right one to protect your musical investment.

Things to Consider When Buying Guitar Humidifier

Acoustic guitars are made of wood or composites, and wood expands and shrinks depending on the humidity levels of its environment. Overexposure at either end is problematic for your guitar, but dryness and heat are the worst enemies.

Worse case scenarios are rarely fun to think about, but if you’re not convinced of the necessity of guitar humidifiers, these potential humidity-related damages should grab your attention.

  • Hairline cracks
  • Fret buzzing
  • Loose bridges and braces
  • Protruding fret ends
  • Separations along the glue joints
  • Top-sinking

Prevention is key!

Guitar humidifiers work to balance the moisture in the air around your guitar, limiting the damaging expansion and contraction of your instrument’s wood.

With this knowledge in mind, you can regulate humidity and keep your guitar in top shape by choosing the best guitar humidifier in the table below.
