YAMAHA HOKAZON Yamaha Hokazon Euphonium/Trombone Mouthpiece - Shoichiro Hokazono - Large Shank This is a large shank mouthpiece, a model designed by Shoichiro Hokazono, a solo euphonium player. It is rumored to be a copy of a Black & Hill 4G. There is a small chip due to an impact. Please check the 5th photo for confirmation before considering a purchase. Other than the above-mentioned damage, it is in very good condition. Shipping included, comes with the original box. I can take more photos if needed. I am also open to reasonable price negotiations, so please feel free to comment.
