Cloth covered aluminum shell and hide-away backpack straps set this viola case apart from most on the market. Lightweight, the Pedi has other ingenious features as well like a music pocket on the bottom if the case. Have you ever had your case tip over from all the music in the pocket on the lid? Cases with music pockets in the lid also put a lot of strain on the hinges, frequently causing them to break over time. A mesh hole in the instrument blanket allows the humidifier to function properly. We like this case so much that several of our staff use them for their own instruments. Available in black, brown, blue, red and olive green.
