Meridian Guitars is a boutique bass manufacturer based in Avezzano, Italy, founded by luthier Davide Cardone. The shop builds instruments largely by hand with traditional luthier tools and uses heavily seasoned tonewoods, often aged for decades before being cut into bodies and necks. Cardone's design language draws on simple geometric forms — most notably the ellipse — and emphasizes the interplay of ergonomics, balance, and aesthetics alongside tone.

The lineup is small and centered on custom-order basses, with models including the Horizon, J-24 (offered in a carbon-topped variant), Mojo II, Amun, Aural II, and the Vimana, a short-scale micro bass with a 22.5-inch scale length. Instruments are available in 4-, 5-, and 6-string configurations and are typically equipped with high-end electronics from outside specialists, including Bartolini pickups and onboard preamps from makers such as John East and Mike Pope.

Meridian operates as a single-luthier workshop rather than a production-line builder, with each instrument assembled to order. The brand has built a following among bass players who follow Italian boutique builders, and its instruments are discussed and traded through forums like TalkBass and on the secondary market via Reverb.

Meridian has 2 products cataloged on Equipboard, including Electric Basses. Their gear is featured by 1 artist, with the strongest followings in Rock and Jazz. Notable users include Ares Tavolazzi.
