With all the same features as the RC series and then some, OSP's SC shock-mount rack cases feature a 1" wall of heavy foam between the outer wall and inner walls where the rack rails are mounted. They also feature egg-crate foam insulation on both the front and back doors for added protection of your rack gear. For over a decade, OSP has been providing quality cases for affordable prices. Whether you're rolling into a different arena every night, setting up and tearing down a portable church every Sunday, or simply taking your amp across town for this week's gig, you'll find an OSP case to be a perfect companion for keeping your gear safe during transport.
