Stringman

Crumar is an Italian manufacturer of electronic musical instruments. It was established by Mario Crucianelli in the late 1960s, and manufactured synthesizers and keyboards during the '70s and '80s. Its name is a portmanteau of "Crucianelli" and the name of his business partner, Marchetti. The company appears to have grown out of the Crucianelli accordion company and also continued to manufacture accordions under both names.
