In the 1930s, Del Vecchio began producing resonator guitars,[1] resulting in their most famous model: the Dinâmico, (their trade term for resophonic instruments).

Current range of products manufactured by Del Vecchio includes classical and resonator guitars, banjos, mandolins, cavaquinho, and viola caipiras.

[2] One of the most famous players of the Del Vecchio Dinâmico resonator guitar was country musician Chet Atkins.

Chet Atkins is credited with playing a Del Vecchio lead guitar on the tune "Turn Around" on Nanci Griffith's Other Voices, Other Rooms.

Though he enjoyed the sound, he was unimpressed with the quality, eventually asking luthier Paul McGill to build him a refined version.
