Ted Klum Alto Saxophone Mouthpiece Acoustimax/amber (amber color) Size 5 I used it with a mouthpiece patch, but when I obtained it, there were already tooth marks. Please check the photos. It's a carefully crafted mouthpiece that produces a dry and warm tone. I liked it and used it for a while, but in the end, the Meyer mouthpiece suits me better, so I'm selling this one. The box and pouch are included. Please understand that this is a used item and purchase with no claims and no returns.
