The Bach TR‑450S is a Bb trumpet built for players seeking professional features in a mid-level instrument. It features an ML (medium large) bore of 11.66 mm (0.459") and a yellow brass bell with a diameter of 120 mm (4 3/4"), designed for a bright, projecting sound.

The bell uses a two-piece design with wire reinforcement along the rim to enhance stability and tonal clarity. The leadpipe is gold brass, valve casings are brass with nickel silver, and valves are stainless steel with aluminum stems. The trumpet has a thumb saddle on the first slide and a fixed ring on the third slide, with a two-piece third valve slide (Stradivarius style).

The entire instrument is silver-plated, giving it a professional, polished finish. Included accessories are a Bach SPS gig bag (with backpack straps), a Vincent Bach 7C mouthpiece, and valve oil. Made in Germany.
