Spectraflex is a U.S.-based manufacturer of instrument and audio cables, founded in 1988 and best known for popularizing the braided-jacket guitar cable. The company markets its flagship product as the "Original Braided Cable," a look that became closely associated with the brand and helped revive woven cloth jackets as a mainstream cable style.

The Spectraflex catalog covers instrument cables (Original Braided, Vintage Braided, Fatso Flex, N-Flex, patch, and personalized series), microphone cables in Hi-Z and Lo-Z configurations, speaker cables, and stereo cables, with most lines offered in both the signature braided jacket and a non-braided "Baldee" version. The cables are assembled in the USA.

Spectraflex cables have been used by a range of guitarists across rock and metal; Dimebag Darrell of Pantera was among the more visible players associated with the brand's braided cables during his career.

Spectraflex has 3 products cataloged on Equipboard, including Instrument Cables and Miscellaneous Guitar Parts. Their gear is featured by 5 artists, with the strongest followings in Rock, Metal, and Pop. Notable users include Dimebag Darrell, Graham Maby, and Amos Heller.
