When not playing your ukulele, or showing it off to your friends, please make sure to keep it in a quality case. We can't stress the importance of this enough. As enjoyable as it would be to hang your new ukulele on the wall as a piece of art, keeping it in a good case will not only protect your ukulele from dings and scratches, but will also help control the range of temperature and humidity it is exposed to. I particularly like any case with a polyfoam liner that helps insulate the ukulele from daily fluctuations in humidity and temperature.
Although we go to great lengths to make sure our wood is dried to the correct moisture content, all solid wood instruments need to be cared for correctly according to the humidity levels of their new environments. This is especially important in dry climates. Too much humidity can create problems, but dry climates can be destroy a solid wood instrument if it is not taken care of correctly.
Try to store your ukulele between 70-75 degrees Fahrenheit, and around 50% relative humidity. Your new baby was born in the tropics, and will surely appreciate a little bit of extra humidity as she adjusts to her new home. Most people don't have a hygrometer to measure humidity, which is why I recommend investing in an in-case humidifier, such as a Damp-It (especially if you live in a dry climate). Damp - It’s are an inexpensive way to ensure that your ukulele is well humidified.
It is often a good idea to store your ukulele in a closet, where it is out of the sun and away from heating and a/c vents. Heating and a/c systems produce very dry air that can create problems for a solid wood instrument.
With a little bit of effort, your new Cocobolo Ukulele should last a lifetime.
