This instrument has now been sold and is preserved in our archive as a historical reference for collectors and players researching high-end Bach trombones.
The 42AF features the classic 8.5" yellow brass bell, paired with a standard weight .547 bore handslide, and is outfitted with a Bach premium hardshell case in pristine condition. Both the valve section and slide performed flawlessly during play testing. The lacquer remains near perfect, and the instrument was fully serviced prior to sale.
This is the top-tier modern iteration of the Bach 42 series, ideal for orchestral and symphonic players looking for a rich core tone, centered articulation, and the smooth feel of the Infinity valve design. At the time of listing, this model sold new for around $4,000 — a serious investment in a professional-level trombone.
