Third Man Hardware is the musical instrument and effects division of Third Man Records, the Nashville-based label founded by Jack White. Rather than manufacturing in-house, Third Man Hardware operates almost exclusively through collaborations with established pedal and instrument builders, with White and the Third Man design team shaping each product alongside a partner company. Releases typically appear in a limited-edition yellow colorway followed by a standard black version.

The catalog spans effects pedals, amplifiers, guitars, and accessories. Notable pedal collaborations include the Triplegraph digital octave with CopperSound, the Troika delay with JHS Pedals, the La Grotte analog spring reverb with Anasounds, the Triple Threat all-analog distortion/phaser/echo with Donner, and the Black Mountain Roto-Echo. The lineup also includes the Knife Drop fuzz and the Holeyboard modular pedalboard system. On the instrument and amp side, Third Man has partnered with Fender on the Jack White Triplecaster and Triplesonic Acoustasonic Telecasters and the Pano Verb amplifier, along with leather strap collaborations.

The brand is closely tied to Jack White's own playing and recording, with several units making their way onto his solo records before reaching the public. Gear from the line has also been used by other artists in the Third Man orbit.

Third Man has 2 products cataloged on Equipboard, including Beginner Kits and Fuzz Effects Pedals. Their gear is featured by 5 artists, with the strongest followings in Rock and Metal. Notable users include Jack White, Matt Pike, and Erik Bickerstaffe.
