The Ted Klum Yardbird is, in a word, an outstanding alto sax mouthpiece. I own three: a hard rubber 8, a gold-plated brass 8, and my latest, a rhodium-plated brass 7. Although I am primarily a tenor player of 20+ years, I picked up alto 6 years ago and now split my playing time 70/30. I tried many different alto mouthpieces over the years, but none gave me the bebop sound I wanted until the brass Yardbirds changed everything. These models made practicing alto a true joy. Their standout features are an instantaneous response, excellent intonation, a powerful sound that never breaks, and exceptional dynamics - ranging from a rich, resonating low register to a full, precise high register. The gold-plated brass 8, which I have been playing for a year, has a slightly more resonant sound than the rhodium-plated 7, but the 7 is easier to play during longer sessions. Both demand harder reeds to achieve the best sound; I rotate between Boston Sax Shop Silver 3, Rigotti Gold 3M and 3.5L, and Vandoren V21 2.5. They require a longer break-in time and yield fewer good ones per box, but they last forever. My current setup pairs the brass Yardbird with a Vandoren Optimum metal tenor ligature, played on a Kessler Custom Handmade red brass alto with a Selmer Paris Series II gold brass neck. Ted Klum’s precision craftsmanship is second to none and his dedication shows in every single note.
