Meticulously crafted, extensively playtested.

The NJS mouthpiece is a Guardala inspired, handmade tenor mouthpiece designed to be warm, moderately focused, and symbiotic with the player. Each one is meticulously crafted and extensively playtested by me. I’ve played Guardalas for nearly all of my years on tenor, and too much of the time found myself struggling to keep my sound from getting too bright and thin. The NJS is my solution, maintaining the character and power of a Guardala, while being richer, warmer, more controllable, and better responding. They are set up to enable the player to really sculpt their sound, sounding better and better the more they are played.


At the start of the COVID-19 pandemic, I began an adventure into metal casting and mouthpiece making, which have become huge passions for me. After years of methodical experimentation and refinement of both skillsets, I have arrived at a product I am very proud of. With NJS mouthpieces, I have sought to create something that honors the traditions of high craftsmanship in the saxophone world; that is made with care, attention to detail, and built to last. You won’t find any unfounded claims or gimmicks here, just my honest impressions and recordings of me playing the mouthpieces. Ultimately, I want my work to speak for itself: each mouthpiece has a 7 day money back guarantee.
