One of the experiences that made Barbara Liebler decide to found Colorado Case Company happened at Rockygrass Bluegrass Festival a few years back. Her friend Cathay locked her acoustic bass in the back of her covered pickup so the two friends could go to lunch. The parking lot is in full sun, and the day was hot, but Cathay left the windows open a bit and they agreed to hurry with the lunch. It took only twenty minutes to stand in the food vendor line, wolf down the lunch, and return to get the bass out of the hot truck. I could could help musicians with this problem.
Moisture damages the instrument, too.
That's why we're serious about insulation and moisture protection, and we test our cases to be sure they are doing that job. Recently we wanted to change the foam interior so that we didn't have to laminate two kinds of foam together. After an extensive search on the internet, Thompson's Register, and in big city yellow pages, we decided on a foam that looked perfect. It was the correct thickness and density, easy to work with but quite substantial. We made a case with this foam from our standard mandolin soft case pattern, then tested it in a hot van parked in sun, along with a mandolin case with our usual foam.
