NK Guitars is a Chinese guitar maker based in Qingdao that specializes in affordable headless electric guitars and basses. The brand sells direct to international buyers primarily through its AliExpress storefront and an active Facebook community, building 6-, 7-, and 8-string headless models in fixed and multiscale configurations. Body shapes are generally Steinberger- and Strandberg-inspired, and buyers can specify woods, finishes, pickup routing, fretboard materials, and other build details when ordering.

The lineup includes models such as the NK Luminous (a glow-in-the-dark inlay variant) and a range of multiscale 7- and 8-string headless guitars aimed at metal and progressive players. Instruments ship with included setup tools — truss rod and bridge adjusters — and a branded gig bag, with most orders fulfilled in roughly five to six weeks.

NK has developed a reputation among online guitar communities (notably SevenString.org and a dedicated Facebook owners' group) as a budget gateway into headless guitars, with most discussion centering on value, customization options, and common upgrades such as swapping pickups, jacks, and wiring. The brand does not operate a traditional standalone website, instead relying on its marketplace shop and social channels for sales and customer communication.

NK Guitars has 2 products cataloged on Equipboard, including Solid Body Electric Guitars. Their gear is featured by 1 artist, with the strongest followings in Rock and Metal. Notable users include Andrew Baena.
