With a lifelong interest in how mechanical things work, Marantz's journey into tech repair and fine detail finish work began as a youngster with a model aircraft hobby in which he built several scale and fully functional flying radio controlled airplane models from scratch. In 2010, Marantz acquired mouthpiece refacing tools and with personal instruction from several highly regarded mentors in the field, began learning the craft of mouthpiece work. As of 2026, Marantz is approaching two decades' worth of experience working directly for several top manufacturers in the worldwide field of mouthpiece making as well as working directly with many world-renowned artists & aspiring professional saxophonists, so he brings a wealth of experience to your next refacing project or custom mouthpiece order. A borderline obsessive attention to detail, experiential depth of knowledge about how a mouthpiece should perform from a player's perspective, and a tireless work ethic are Marantz's primary strengths as a mouthpiece technician.
