Bach 42BOF Open Flow, European Style Open Wrap Tenor Trombone- SN 219822 This slightly used example was purchased new by its previous owner and played very little. It is in perfect condition, with flawless lacquer, and has never been damaged or repaired. Unlike “open box” or demo models, this horn was originally sold as factory new, not a discounted return or B-stock item.
It features the classic Bach 42 one-piece yellow brass 8.5" bell, finished in gorgeous clear lacquer. The standard weight Bach 42 handslide is in excellent condition and received an in-shop professional setup to optimize action and responsiveness. The inner tubes are straight and clean, with no plating loss.
This model is equipped with the Meinlschmidt-designed open flow rotor, a European-style open wrap valve that is smoother, quieter, and more free-blowing than the traditional 42BO rotor. For players looking to upgrade from the standard 42BO, this is a noticeable improvement in both feel and response.
What does “open box” really mean when buying a trombone online?
It’s a term used frequently, but not always clearly. “Open box” might suggest a product returned after brief use, a unit with cosmetic issues, or even one with a factory defect—perhaps a slide that didn’t meet spec or needed repair. While open box deals can save money, they may also come with uncertainty. At The Brass Exchange, we prioritize clarity and quality—our customers typically want the best condition possible, especially when investing thousands in a professional-level instrument.
A new Bach 42BOF retails for $4829. This one is priced well below that, yet offers zero compromise in condition or performance.
Includes the original factory case in perfect condition. Mouthpiece not included. In stock now for immediate delivery. Will not disappoint.
