As I take the train from New York City to Sommatone Amplification in Somervilles, New Jersey, lush greenery and farms flash by the window and it’s easy to see why the area is called the Garden State. The Sommatone factory is actually part of a three-car garage nestled in the woods behind a ranch-style house abutting a large swimming pool. This is where Jimmy Somma designs and builds some fantastic-sounding heads and combos.
