Naylor Engineering is an American guitar amplifier company specializing in handcrafted tube amps, speakers, and cabinets. Co-founded in the early 1990s by Joe Naylor and Kyle Kurtz, the company initially produced speakers before branching into full amplifiers in 1994. Joe Naylor left in 1997 to launch Reverend Guitars, and in 1999 David King acquired the brand and moved operations to Dallas, Texas.

Naylor amps are point-to-point hand-wired on linen-grade phenolic eyelet boards using heavy-gauge wire and premium components. The lineup has included models such as the Electra-Verb 60, Super Club, Duel-60, and SD-60, typically voiced for a fat, harmonically rich tone with a throaty midrange and tight low end. The brand also produces matching speakers and cabinets designed to pair with its amplifier line.

Naylor developed a following on the Nashville session and touring scene and is often associated with boutique American tube amp builders drawing on classic 1960s amp circuits while pursuing their own voicing.

Naylor has 3 products cataloged on Equipboard, including Guitar Amplifier Heads and Combo Guitar Amplifiers. Their gear is featured by 7 artists, with the strongest followings in Rock, Pop, and Hip Hop. Notable users include Ron Asheton, Scott Shriner, and Tommy Lee.
