Carlo Robelli is the house brand of American retailer Sam Ash Music, covering a broad catalog of budget and intermediate-priced instruments sold almost exclusively through Sam Ash channels. The name first appeared in the 1960s on imported violins and was extended in the 1970s to a line of guitars built in Japan by Fuji Gen-Gakki, the same factory responsible for early Ibanez and Greco models. Those vintage Japanese Carlo Robellis were largely copies of popular American electric designs and are sometimes grouped with the so-called lawsuit-era imports.

The brand was revived in the 2000s and now spans acoustic, electric, classical, and bass guitars alongside violins, violas, cellos, double basses, mandolins, banjos, ukuleles, and solid-state amplifiers. Production has shifted through several regions over the decades, including Brazil (by Giannini), South Korea, Indonesia, and China, with final setup often handled in-house at Sam Ash. Typical catalog models include the F-series dreadnought acoustic-electrics, the CR-series student and step-up violin outfits, and various beginner electric and bass packages.

Carlo Robelli occupies the entry-level-to-intermediate tier of the market, positioned as an affordable option for students, beginners, and players looking for a second or travel instrument rather than a flagship. It has no signature artist roster in the traditional sense; its presence is defined less by endorsements than by its role as Sam Ash's in-house label for value-priced gear.

Carlo Robelli has 15 products cataloged on Equipboard, including Acoustic-Electric Guitars, Violins, and Semi-Hollowbody Electric Guitars. Their gear is featured by 4 artists, with the strongest followings in Rock, Funk / Soul, and Folk, World, & Country. Notable users include Rob Scallon, Joe Dart, and Jack Stratton.
