Soft German felt general cover with no base felt on 1.5” x 3/8” convex felt core. The super 2. This model was inspired by my Duff #2 model but with a core that is one and a half times the size and on a bamboo shaft with a much thicker and softer covering. It’s really a general stick with a clear sound and a lot of fundamental to it. Perfect choice for Sibelius Finlandia, Young Person’s Guide to the Orchestra, many Beethoven Symphonies, Brahms Symphonies, Tchaikovsky, Mahler and Bruckner.
