JLB Wooden Sleeve - Sound Enhancement System
This sleeve is an invention of Josh Landress. This Wooden Sleeve Enhancement System, (WSSES) is designed to help slotting, projection, response, and less of a work effort. The sound that is produced with this sleeve is large and robust. After experimenting with different types of material, Josh has found that cocobolo wood is the optimum material, and it fits over most popular brands of mouthpieces. All of these sleeve's are made in shop in New York City by hand. The way this sleeve stays on the mouthpiece is with a little stop screw that you can unscrew at anytime with an Allen key.
