HILS Guitars is the international brand of Hex Guitars, a Korean manufacturer that has built instruments for other companies since the early 2000s before launching its own label. Production is based out of the company's own factory in Indonesia, a setup the brand uses to offer higher-end features — roasted maple necks, stable hardware, and ceramic pickups — at more accessible price points. The name HILS is associated with Hex Instrument Labs.

The lineup centers on headless electric guitars and basses in the NEXT series, including the NEXT HN3, HN4, and HN5 models, along with the HNT1 T-style and HNS1 S-style headless designs and the NEXT HNB5 multi-scale 5-string bass. Beyond the headless catalog, the brand also offers more traditional electric and acoustic models such as the TALENT, HERO, and BLUFFTON.

North American distribution is handled by HILS America, operated by Second Chance Warehouse LLC out of Bluffton, Indiana, where instruments are set up and inspected before sale. The brand is also stocked through international retailers including Andertons in the UK, Thomann in the EU, and Max Guitar in the Netherlands.

HILS Guitars has 3 products cataloged on Equipboard, including Solid Body Electric Guitars.
