The Blair Bollinger Model Bass Trombone was developed through the close collaboration of Blair Bollinger, Steve Shires, and the craftsmen of S. E. Shires. The resulting instrument is genuinely unique and includes several specific design elements not found on any other S.E. Shires trombone.
Bollinger Bell: 9.5-inch, two piece, hand hammered Bollinger taper in medium weight yellow-brass with traditionally brazed seam and soldered bead
Independent, S.E. Shires axial-flow valves with optimized lever geometry and Bollinger Tuning System™ (tuning slide for conventional G? tuning included)
Tuning Slide: Bollinger taper tuning slide in drawn yellow brass
Bollinger Handslide: .562/ .578-inch dual-bore, custom-weight slide with yellow-brass outer tubes, yellow-brass crook, and tone-enhancing mouthpipe collar
Three interchangeable yellow-brass leadpipes Bell Engraving: S.E. Shires Blair Bollinger model custom engraving
