Get Quality Craftsmanship with The S.E. Shires TBBO Blair Bollinger Artist Model Bass Trombone with Bollinger Tuning System Axial-Flow AttachmentThe Blair Bollinger Model Bass Trombone was developed through Blair Bollingers close collaboration with 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. The Bollinger Tuning System facilitates playing scales and arpeggios with the smallest number of handslide positions possible. Custom lever geometry requires a shorter throw, making these the fastest axial-flow valves available anywhere. The weighted mouthpipe collar, custom-weight dual-bore handslide, and unique tuning slide provide quick response and clear articulations while retaining the density and color of yellow brass. A custom weighted tuning slide further pairs a quicker response with the larger sound and feel of our C taper tuning slide. Complimented by the yellow-brass Bollinger bell, this instrument produces a broad orchestral sound with unparalleled response and clarity.SPECIFICATIONSBollinger bell:9.5-InchTwo-PieceHand-Hammered Bollinger TaperMedium WeightYellow BrassTraditionally Brazed Seam And Soldered BeadIndependent, S.E.
