Callaham Vintage Guitars and Parts is a small family-run manufacturer of replacement hardware for vintage-style electric guitars, based in Winchester, Virginia. The company was founded in 1989 by Bill Callaham, a Virginia Tech mechanical engineer who grew up around machine shops and vintage instruments such as Lloyd Loar mandolins and 1950s Gibsons and Fenders. Callaham started in a basement, moved to Berryville, and eventually settled in Winchester, supplying dealers internationally and direct customers worldwide.

The shop is best known for its precision-machined Stratocaster and Telecaster hardware, including the Vintage S Model Strat bridge assembly, the Vintage Hardtail bridge, the V/N Strat bridge, cold-rolled steel tremolo blocks, compensated Tele saddles, and Tele bridge plates. Callaham also produces parts for Gibson and Bigsby-equipped instruments, with the focus on reproducing the materials, tolerances, and tonal character of pre-CBS-era components rather than chasing cosmetic vintage appeal.

In earlier years the company also built complete handmade S- and T-style guitars and a line of tube amplifiers, though Callaham has since narrowed its catalog to parts and hardware. The brand has a long-standing reputation among tone-focused players, luthiers, and guitar techs for the consistency of its machining, and its tremolo blocks and bridge assemblies are common upgrades in custom builds and high-end Strat and Tele restorations.

Callaham has 2 products cataloged on Equipboard, including Guitar Bridges and Tailpieces.
