SKB is an American manufacturer of protective cases, founded in 1977 by Dave Sanderson and Steve Kottman in Anaheim, California. The company built its first guitar case in a residential garage and has since expanded into a wide catalog of cases serving music, pro audio, photo/video, sports, and industrial/military markets. SKB is headquartered in Orange, California, with a European arm (SKB Europe) supporting international distribution.

Within music and pro audio, SKB produces hard-shell instrument cases for guitars, basses, drums, keyboards, and orchestral instruments, along with rack cases, mixer cases, microphone cases, and pedalboard cases. Product lines include the iSeries waterproof injection-molded cases (built to MIL-STD-810 standards), the roto-molded shock rack series, and the lighter Hybrid and Universal shaped guitar cases. The company also offers stagehand-style utility cases and custom interior foam options.

SKB cases are widely used by touring musicians, audio engineers, and rental houses, and are stocked through major music retailers including Sweetwater, Guitar Center, and Music & Arts. The brand is generally regarded for durable, road-ready protection at price points spanning entry-level molded cases up through flight-rated ATA touring cases.

SKB has 44 products cataloged on Equipboard, including Bags & Cases, Pedalboards, and Studio Equipment Racks. Their gear is featured by 17 artists, with the strongest followings in Rock, Pop, and Blues. Notable users include Shane Moran, Bill Kelliher, and Dave Matthews.
