Fast Guitars is a boutique electric guitar and bass builder based in Vancouver, British Columbia, Canada. Founded in 2006 by Kevin Fast, the company grew out of an OEM (original equipment manufacturer) operation that built bodies, necks, and complete instruments for other brands before launching a proprietary line under the Fast Guitars name.

The lineup features models such as the Roamer, an offset-bodied solid with a belly cut; the Orion, built around a bound, drop-top solid-wood design; and the Falcon, a headless single-cut. Other models in the catalog have included the SS, JazzMonster, and NorthStar. Construction details emphasized by the builder include tapered-tenon bolt-on neck joints, spoke-nut truss rods with heel access, and CNC-machined cavities paired with hand finishing.

Fast Guitars sits in a small category of Canadian shops that operate as both contract manufacturers and their own-brand builders, which the company has positioned as giving it access to production-scale tooling while retaining the flexibility of a custom shop. The brand has a presence on Reverb and maintains social channels where new builds are documented.

Fast Guitars has 5 products cataloged on Equipboard, including Solid Body Electric Guitars, Electric Basses, and Extended Range Guitars. Their gear is featured by 5 artists, with the strongest followings in Rock and Metal. Notable users include Andrew Baena, Matt Perrin, and Johnny Ciardullo.
