Why do you need a humidifier? Well the answer is that the majority of our ukuleles are made of wood. While Flight has crafted their ukes to exacting, artful specifications, wood is always subject to slight changes according to how much moisture is in the air. If you live in an area where there is little humidity, then the wood of any instrument can dry and warp causing issues with playability- fret buzz, dead string sounds etc. At worst it can result in the wood cracking. At Flight they like to balance quality with affordability. We are proud to be able to supply you with this invaluable tool for ensuring you can play all year round without the climate affecting your treasured instrument. By gently adding a little bit of moisture into the air around your instrument, your uke won't be able to tell the difference if it's living in Mexico or Manokotak. Flight loves their instruments and want to make sure you continue to enjoy them. If looked after properly, they will last for generations!
