Abstract: An improved musical instrument carrying case combines a well-placed storage space for bows and accessories with a humidity control system to completely protect and preserve the instrument. The case includes a base and an upper lid which together form the outer surface of the case. Inside the case, a lower lid divides the case into two compartments. A first compartment is formed between the lower lid and the base of the case, while a second compartment is formed between the lower lid and the upper lid. The first compartment is preferably lined with a protective padding which has a molded primary chamber for the instrument. In addition to the primary chamber, a humidity control system and an accessory chamber are preferably between the lower lid and the base of the case. Within the second compartment is a cache for a plurality of bows or other accessories. By separating the instrument and bows into two different compartments, the life of bow hairs and the wooden body of the instrument is prolonged.
