Tuttle Guitars is a California-based boutique builder founded by luthier Michael Tuttle, who established the company in 2003 after years of experience that included work with Valley Arts and time alongside Don Grosh. Tuttle began building guitars in the early 1980s and started commercial production in 1993, eventually launching his own brand focused on handcrafted electric instruments built in small numbers.

The shop is best known for its take on classic bolt-on designs, with models including the Custom Classic S and Custom Classic T, the Tuned S and Tuned T, the Custom Classic Thinline T, the J-Master, and the Carve Top Standard, Supreme, and Deluxe. The instruments are recognized in the boutique community for their fretwork, neck feel, and overall fit and finish, summed up by the company's own tagline of "Best Feel, Best Tone, Best Frets."

With Michael Tuttle and a small team handling each build personally, output is limited and quality control is hands-on rather than production-line. The brand has earned a reputation among players who favor traditional S- and T-style electric guitars but want premium tonewoods, refined detail work, and meticulously dressed frets.

Tuttle has 1 product cataloged on Equipboard, including Solid Body Electric Guitars. Their gear is featured by 1 artist, with the strongest followings in Rock, Funk / Soul, and Jazz. Notable users include Louis Cato.
