Boston Sax Shop S-Series mouthpiece for alto saxophone

"Inspired by the past, created for the future".
This is a reference to the great "horseshoe" chambered mouthpieces of the past, but made for the modern musician. 
 
From the Boston Sax Shop website:
"I've been lucky enough to enjoy some amazing classical mouthpieces and have been constantly on the lookout for a mouthpiece that has tonal homogeneity in all ranges, but can get a lot of volume. The S Series hard rubber alto saxophone mouthpiece is the result of that search and I am proud to share a design that, in my opinion, packs a remarkable amount of body, depth and evenness for a "jazz" mouthpiece, while still having the ability to break through and project. It is a reference to the great "horseshoe" chambered mouthpieces of the past, but made for the modern player. 
The creation of the BSS mouthpiece line has also given me the opportunity to approach the boutique market with a new methodology. After much research, we partnered with one of the most advanced CNC machining shops in the country, allowing us to achieve an incredible level of precision and absolute consistency piece by piece. You don't have to worry about getting a "good one" because they're all great. Plus, each one is hand-finished in the shop and personally tested by yours truly."
