Mastering Studio

The Nagasaki Sound mastering studio (we call it The Bunker) is located in the beautiful Southwestern USA, within easy reach of Las Vegas and Phoenix. A secluded desert setting (and thick rammed-earth/stone walls) acoustically isolates the mastering studio from the outside world. The Bunker’s minimal fusion of industrial and Japanese design breeds creative energy. Reflecting his DIY aesthetic, Steve Nagasaki designed and hand-built the custom mastering console, mastering studio furniture, acoustic treatment, and lighting system. From the mightiest metal blastbeats to the nastiest dubstep wobble, the bunker is the perfect listening environment for Steve to focus on your audio. Some of our mastering studio gear is listed below.
