Halo Custom Guitars is a family-owned instrument builder based in Cupertino, California, founded in 2004 by Belinda Lee. The company specializes in custom-built electric guitars, basses, necks, and bodies, offering musicians the ability to configure instruments to their own specifications through an extensive online configurator. Halo produces both production-line models and fully bespoke commissions through its Custom Shop program.

The catalog spans a range of body styles including solid-body electrics, archtops, hollowbodies, and acoustic guitars, with the TJ Baritone among its notable production offerings. In addition to finished instruments, Halo supplies guitar bodies, necks, and DIY kits for builders and hobbyists. The brand occupies a niche in the build-to-order market, catering to players looking for personalized spec choices—woods, hardware, pickups, finishes, and scale lengths—without commissioning a boutique luthier at boutique pricing.

Halo Custom Guitars has 14 products cataloged on Equipboard, including Solid Body Electric Guitars and Extended Range Guitars. Their gear is featured by 7 artists, with the strongest followings in Rock, Metal, and Electronic. Notable users include Eddie Van Halen, Will Swan, and Ola Englund.
