Gladiator is a line of electric guitars distributed by Saga Musical Instruments, the San Francisco-based importer also responsible for Blueridge acoustic guitars, Kentucky mandolins, Gold Star banjos, and Gitane gypsy-jazz guitars. The Gladiator range debuted in 2010 and centers on affordable Fender-inspired bolt-neck designs, with S-style (Stratocaster-shaped) and T-style (Telecaster-shaped) bodies offered across Modern, Vintage Modern, and Vintage tiers. Typical model designators include the GL-111 S-style, the GL-121 T-style, and the GL-221 Vintage Series Telecaster.

Lower-tier Modern models are built around basswood bodies with ceramic pickups, sealed tuners, and cast bridge saddles, while the Vintage Series steps up to ash bodies, Alnico Wilkinson pickups, bone nuts, and vintage-style hardware such as closed-back tuners and rolled saddles. The instruments are produced overseas and sold through small and mid-size dealers rather than the large chain retailers, which has positioned the line as a budget alternative to Squier and similarly priced import S-type and T-type guitars.

Gladiator is sometimes confused with unrelated guitar-pedal products that share the name, including the DemonFX Gladiator and AD Pedals Gladiator overdrives, which are made by separate manufacturers and are not part of the Saga lineup.

Gladiator has 2 products cataloged on Equipboard, including Solid Body Electric Guitars and Synth Plugins.
