 Callet's involvement with the business of instruments began with sixteen years in sales (1953-1968) for Elden Benge, followed by eight years of experience with Dominick Calicchio (1968-1975).He absorbed much of his knowledge of trumpet making from these two brilliant men.With this rich background and his talent as an accomplished machinist, Callet launched his experimental trumpet design in 1956, and started selling his own trumpets under the Callet brand in 1984.
