I needed a pair of matching cases for an acoustic violin as well as my YEV 5 string electric. I wanted something affordable, sharp-looking, and had a few additional must-haves (subway strap, shoulder/back sling-strap, space for shoulder rest/rosin/etc). These GEWA Bio-S cases fit the bill perfectly. Sadly, when I placed the order for two, they were backordered for *months*, but it was SO worth the wait! I've been regularly gigging with both instruments, and wouldn't have changed a thing about my order!
