The Jacobacci brand was founded in the Parisien district of Menilmontant during 1920s by Vincent Jacobacci. Jacobacci was an Italian immigrant from Catania, who began by making banjos and guitars. Vincent's son Roger Jacobacci, decided in the early fifties to start making electric guitars, initially by adding pickups to the existing Jacobacci acoustic guitars.
Jacobacci built guitars for the Major Conn Paris store following an agreement in 1956, and these guitars have the brand name Major. Major models included the Royal, the Soloist and the Super Deluxe. Other models included the semi-hollow bodied Texas and the solid bodied Ohio. Some famous French rock and roll bands (like Johnny Hallyday, the Pirates and the Vatours) played the Texas and Ohio models, increasing the desirability of Jacobacci guitars with the French public.
