J. Rusty Shaffer  founded Optek Music Systems to manufacture and distribute the Smart Light (later Fretlight) Guitar and learning system which he invented in 1987. These guitars have LED lights embedded into the fingerboard to show learners where to put their fingers. The earlier models were branded Smart Light (SL) and in 1998 Optek went into partnership with Washburn International to market the Washburn SmartLIGHT Guitar. Some of the SmartLight guitars were manufactured by Samick. Optek Music Systems has now discontinued the SmartLIGHT brand name in favour of the Fretlight brand.
