IYV is the brand name used by Inyen Vina, a Korean-owned guitar manufacturer operating out of a factory in Ho Chi Minh City, Vietnam. The company has built a reputation as a large-scale OEM producer, making instruments for a number of well-known budget and mid-tier guitar brands, and sells a wide catalog of its own models directly through retailers such as Reverb, Amazon, Guitar Center, and Musician's Friend.

The IYV lineup spans solid-body electrics, semi-hollow and hollow-body electrics, basses, and acoustic guitars, with shapes covering most of the familiar Strat-, Tele-, LP-, SG-, ES-335-, Jazzmaster-, and Mustang-inspired silhouettes. Pickup configurations include HH, HSH, and SSS setups, and instruments are built using tonewoods such as mahogany, maple, and jatoba. The brand is positioned at an affordable price point, typically competing with import-tier offerings from Squier, Epiphone, and similar value-focused lines.

Among players and forum communities, IYV is often discussed as a "sleeper" value brand — instruments that punch above their price class thanks to the factory's experience producing guitars for larger OEM customers. The catalog emphasizes breadth over signature artist models, aimed at beginners, hobbyists, and builders looking for partscaster-friendly platforms rather than flagship showpieces.

IYV has 13 products cataloged on Equipboard, including Solid Body Electric Guitars, Semi-Hollowbody Electric Guitars, and Hollowbody Electric Guitars.
