Additional Resources


  • What is the #1 cause of all instrument repairs?

    Lack of humidity is the leading cause of all instrument repairs. It is essential to humidify all wooden instruments.

  • How do I recognize symptoms of a dry instrument?

    A dry instrument can be recognized by a number of symptoms. Sharp fret ends, neck bow, sunken top, lifted bridge, lower string height, notes starting to buzz, cracking of the neck and/or body, or change in tone of the instrument.

  • Which Humidipak do I need?

    If your instrument is not already too dry, Humidipak Maintain will maintain a constant relative humidity level inside your case. If your instrument is dry and needs to first be brought back to the proper relative humidity level, use Humidipak Restore. If you're already in a high-humidity environment and need to lower the relative humidity of your instrument, use Humidipak Absorb.

  • How often should I replace my Humidipak?

    Humidipaks typically last between two to six months for an instrument that is already preconditioned to 45%-50% relative humidity. They should be replaced when the packets begin to feel hard or every six months maximum, whichever comes first.

  • What temperature should I keep the room my instrument is stored in?

    It's important to maintain a consistent temperature in the room where your instruments are stored. Anywhere in the range of 70-76 degrees Fahrenheit is ideal.
