Vic Firth SRM Rod Morgenstein Signature Series Drumsticks Combine a 5B and a 2B. The SRM features a full shoulder for endurance. Each Vic Firth Signature Series model was conceived through extensive research with the finest drummers from a variety of musical styles. The designs reflect their musical requirements in terms of balance, feel, sound projection and cymbal color. All colored sticks feature a clear, natural tip. All sticks are hickory unless otherwise noted.
