Strictly 7 Guitars (S7G) is a guitar maker founded in 2007 by Jim Lewis and based in Medina, Ohio. As the name suggests, the company originally focused on seven-string electric guitars aimed at heavy and progressive metal players, but the lineup has since expanded to include six-, eight-, and nine-string guitars as well as bass guitars. S7G operates partly as a custom shop, offering hand-built USA instruments where players can specify tone woods, pickups, hardware, and scale length, including multi-scale (fanned-fret) configurations.

Signature model shapes include the Cobra electric guitar and a family of bass models named after snakes — the Copperhead, Sidewinder, and Python. In addition to the USA-built custom instruments, S7G has a Japan-built production line distributed through Shimamura Music and ESP's BIGBOSS retail network. The brand has also collaborated with Gruv Gear on S7G-branded FretWraps.

S7G has worked with a number of metal guitarists over the years, most notably producing an early run of Ola Englund signature seven- and eight-string models under the Solar name before Englund spun Solar off into his own brand. The company's ergonomic focus, extended-range specialization, and willingness to take on unusual custom builds have given it a dedicated following within the djent and progressive metal communities.

Strictry 7 Guitars has 2 products cataloged on Equipboard, including Electric Basses and Extended Range Guitars.
