The Blessing B-88-O (or BTB-88-O) is an intermediate to professional-level large-bore Bb/F tenor trombone. Revered as a cost-effective alternative to the classic Conn 88H, it features an open-wrap F-attachment with a traditional rotary valve, an 8.5-inch bell, and a robust sound ideal for advancing students.
Key Specifications & Features
Key: Bb/F (with a traditional rotary valve)
Bore Size: Large 0.547” bore for a rich, full symphonic sound
Bell: 8.5” diameter, available in either yellow brass (for clear projection) or rose brass (for a darker, warmer tone)
Wrap: Open wrap design that provides a freer-blowing, less-resistant feel in the upper register
Slides: Chrome-plated nickel silver inner slides and a nickel silver or yellow brass outer slide
Historically manufactured in Elkhart, Indiana, older U.S.-made models are highly sought after by budget-conscious players looking for professional-tier performance. Modern iterations—now part of the Blessing Performance and BTB-1488 series—continue to be trusted by band directors for their durability and playability.
The trombone has been manufactured in Elkhart and is almost identical to Conn 88H trombones, the instrument has been through a full service with slide alignment and playable out the case (Conn case).
