Troy, I am going to brush Concrobium in it and that should keep the mold out for a long time. Try the rice drying method and see if it works for you. I was reading that this is how they remove moisture from cell phones when they get wet, just with a lot more rice. I love the sound of the Vibrandoneon to much to keep it in the case. By the way they quoted $500 to install a (3) mic pick up from Sennheiser with volume control. What are your thoughts about a built-in pickup vrs one that just attaches from the outside. I kind of don’t want to have any holes drilled into the wood.
