Canadian Brass Gene Watts Signature Trombone Mouthpiece (Large Bore) Gold Plated Thank you for looking. This is a Canadian Brass Gene Watts Signature Trombone Mouthpiece (Large Bore) Gold Plated. Details are unknown, but it was purchased at Yamaha Shinsaibashi store in the late 1990s. I used it as my main mouthpiece for several years after switching from a Bach 5G. The reason for switching was that the rim felt good on the lips, it was easy to handle, and it produced a brighter tone (I was once told that a Bach 5G produced a German sound on an American horn). This is a very rare mouthpiece as it is now discontinued, but it is in extremely good condition, showing little sign of its age. - Model: G2 - Rim Size: Inner diameter 25.5cm, Rim thickness 6mm, equivalent to Bach 5. Rim shape is slightly flat. - Cup Size: Deep, but with a slightly acute conical shape. Used for several years. It has been cleaned. The gold plating is in good condition, but the shank has thinned due to use. However, there is still plenty of plating remaining. Returns due to a mismatch in feel are not accepted. Thank you for your understanding.
