In 1976, in Milan, Gioachino started his own activity dedicating himself to the construction of plucked instruments, both folk and classical, and in 1983 he focused exclusively on classical guitars, paying particular attention to the new acoustic- environmental needs of the instrument. His considerable production allows him a wide range of experimentation, such as to validate his personal acoustic research. He gains an excellent success at international level with the appreciation of guitarists of worldwide fame.
