OSP is an Arkansas-based manufacturer of protective cases and gear-transport solutions for musicians, audio engineers, DJs, and live-event professionals. The company specializes in affordably priced ATA flight cases, equipment racks, mixer cases, guitar amp cases, speaker cases, utility cases, and pedalboard cases such as the FX1624 24-inch pedalboard with ATA case. Their PRO-WORK series of drawer workstations — including the PRO-WORK-SXS side-by-side ATA drawer case — are commonly seen in touring backline and portable production rigs.

OSP cases are typically constructed from 3/8-inch plywood with aluminum edging and high-impact ball corners, positioning the brand as a budget-friendly alternative to higher-end road case makers.
