My alto saxophone mutes are now for sale through Merdian Winds in Okemos, Michigan! In addition to my mutes, they have lots of really great saxophone accessories to purchase. I recommend checking out their Ergonomic Heavy Mass Neck Screws - they really make a big difference! Thanks Eric for including my mutes with all of your fine products!
