GJ2 Guitars is an electric guitar manufacturer founded in 2011 by luthier Grover Jackson and Jon Gold, a former senior international sales executive at Fender. The company builds its instruments at a small shop in Southern California, where Jackson — best known as the founder of Jackson Guitars and the designer of Randy Rhoads' Concorde — returned to hands-on guitar making after years away from his namesake brand.

The lineup centers on a handful of solidbody models including the Arete (a neck-through design offered in 3-Star, 4-Star and 5-Star variants), the Concorde (a neck-through with a 25.5-inch scale that nods to Jackson's classic shapes), the bolt-on Glendora, and the Zora, which was developed with input from Tom Dumont of No Doubt. Build details such as PLEK-machined fret work and CNC-assisted neck shaping are emphasized across the line.

GJ2 occupies a boutique niche aimed at players who want a Grover Jackson-designed instrument in modest production numbers rather than a mass-market guitar. The roster of associated artists has included Tom Dumont and Mick Murphy of My Ruin, among others.

GJ2 has 2 products cataloged on Equipboard, including Solid Body Electric Guitars. Their gear is featured by 2 artists, with the strongest followings in Rock and Blues. Notable users include Tom Dumont and Laura Cox.
