Athos worked as electronics engineer in the Italian aircraft industry in the second world war. When the war finished he started a small workshop, and within a few years he was designing and building innovative vacuum tube devices. He founded the  Davoli Krundaal company in Parma in 1957.
At the start of the 1960s Davoli started making instrument amplifiers and P.A. systems, which rapidly caught on in Italy, soon most of Italian bands and many foreign bands touring in Italy were playing and singing through Davoli amplification systems.

In the 1960s, Davoli started a partnership with Antonio Poli “Wandre”, the visionary electric guitar designer who lived from 1926 to 2004. Their collaboration led to a series of ground-breaking guitar designs.
