Guilford Guitars is a small American electric guitar and parts maker based in Glasford, Illinois, founded and run by luthier John Guilford. The company builds boutique solid-body electrics including the Ty Tabor signature model, RX88, Atlas, Redeemer, Crown, and the Blaze (a signature design developed with Steve Blaze of Lillian Axe).

Alongside complete instruments, Guilford is widely known among builders and modders for its wooden hardware components — pickup rings, pickup covers, truss rod covers, back plates, knobs, and tremolo blocks — crafted from exotic and figured woods. These parts are sold direct through the Guilford site and through Reverb, where they're popular as drop-in upgrades for production guitars.

The brand has built relationships with players such as Ty Tabor of King's X, Steve Blaze of Lillian Axe, and Damon Johnson, with the Ty Tabor model in particular reflecting years of refinement in collaboration with the artist.

Guilford has 3 products cataloged on Equipboard, including Solid Body Electric Guitars and Acoustical Treatments. Their gear is featured by 2 artists, with the strongest followings in Rock. Notable users include Ty Tabor and Bruce Bouillet.
