Liutart is an Italian luthier workshop founded in 1990 by Roberto Bertoni, based in the Brescia province of northern Italy. The company specializes in handmade electric guitars, hollow-body guitars, and bass guitars, alongside pickups, strings, and electronics. Their guitar lineup includes solid-body models like the Nytro (available in 7-string configurations), Fusion, New York, Flyght, and Los Angeles, as well as hollow-body instruments such as the Simphony, Venice, and Florence. On the bass side, the J-Funk and J-Fusion are offered in 4, 5, and 6-string versions with fretted or fretless options. The company also produces guitar and bass pickups, including the PS90 and VBB models.

Under the companion Tube Art brand, the workshop produces effects pedals, power boosters, on-board active electronics, pedalboards, and accessories. Liutart instruments have been used in studio and live settings by players working with prominent Italian artists including Vasco Rossi, Nek, and Eros Ramazzotti. Australian-Welsh blues guitarist Gwyn Ashton has a signature model, the L.A. Gwyn Ashton, which combines a Gibson Firebird-inspired body with a Liutart PS90 neck pickup, Seymour Duncan Lipstick middle pickup, and a Liutart VBB bridge pickup — a configuration Ashton designed as his ideal slide guitar.
