  1. My ukulele is made in California and I’ve heard that if it wasn’t made in Hawaii then it doesn’t need a humidifier, is this true? Please Help!!!

    1. Hey Faith!

      Thanks for being a part of the Underground – that’s a great question. Actually, it doesn’t matter where your ukulele is made, if it is made out of wood, it should be kept at a specific humidity (the optimal humidity is around 40-50%). So if you check your local weather report and it says that the current humidity is below 40%, you should probably put a humidifier in your ukulele case. Low humidity can affect any and all wood instruments and can lead to exposed fret ends, changes in playability, or even separation of the wood pieces and cracking (if the humidity is lower than 25% you definitely need a humidifier).

      The misconception may come from the fact that ukuleles made in Hawaii tend to be made out of koa wood, which is generally a softer wood (and more expensive), so people tend to take more care of controlling the humidity for these because they’re more susceptible to cracking at low humidity (and more expensive to repair or replace). However, ALL wood is susceptible to changes in humidity, so if you live in an area that’s naturally dry, definitely get a humidifier to protect and extend the life of your instrument.

      Hope that helps and if you have any other questions, we’re always here for you!
