"Player's Grade" Bach Stradivarius 42BO Trombone - Custom Valve Section

For sale is a Bach Stradivarius Model 42BO Tenor Trombone, serial number 129572 (c. 1997). This is a true "Workhorse" instrument. It features the desirable Open Wrap (BO) attachment and has been upgraded with a Custom Vertical Rotary Valve (likely an Axial Flow/Thayer style conversion). While the lacquer has seen better days, the slide is smooth and the sound is massive—classic Elkhart Bach power.

This is the ultimate bargain for a college student, gigging pro, or serious amateur. If you don't care about shiny lacquer and just want a horn that sounds like a $4,000 symphony instrument, this is it. It’s perfect for the player who wants top-tier performance without the stress of scratching a pristine horn in the pit.

The "Sleeper" Specs

Don't let the looks fool you; under the hood, this is a hot rod.

  • Custom Vertical Valve: Unlike the standard "stuffy" rotary valves found on stock 42s, this horn features a custom vertical valve setup. This design aligns the air path more directly, significantly reducing resistance in the F-attachment. The result is a low register that speaks as freely as the open horn.
  • Elkhart Bell: Features the legendary 8.5" One-Piece Hand-Hammered Yellow Brass Bell stamped "Elkhart, IN." This bell produces the signature warm, broad, and projecting sound that has defined the symphonic trombone section for 50 years.
  • Open Wrap (BO): The F-attachment tubing features fewer bends (Open Wrap), further contributing to a free-blowing feel.

Condition Report: "Battle Scarred"

  • Aesthetic: This horn is in "Player's Condition." The lacquer is heavily worn ("yuck" is an accurate description!), with spotting, scratches, and acid bleed typical of a well-loved professional horn.
  • Body: Shows evidence of prior dent repair and battle scars throughout.
  • Slide: Despite the cosmetics, the slide action—the most important part—is good and ready for performance.
  • Valve: The custom valve moves freely and seals well.
