Thank you for viewing! J. Michael (Mac Corporation) TR-400 Key of B♭, Bell Diameter 120mm, 2-piece bell Amado key valve functions normally, ML bore 11.68mm, suitable for beginners to experienced players. Pistons are smooth. The 3rd trigger allows for smooth pitch correction during performance. After pre-treatment, lacquer stripped with solvent, stitch processing, brushed-up satin finish, rust prevention spray applied. Produces a vibrant tone with a dry tone, very jazzy in appearance! No pitch discrepancies across the range. Original semi-hard case: zippers, Velcro, handle hinges are all in good condition. No odor inside the case. Some minor dirt on the exterior. Mouthpiece: J. Michael MTP-5, standard type. Some scratches on the rim, but does not affect playing. Soaked in baking soda and citric acid solution for 2 days, then the inside of the tubing was cleaned with a neutral detergent and wire brush to remove mold and dirt, ensuring a hygienic condition. Ready to play upon arrival. With its light and responsive feel, this is a pocket trumpet that's too good to just practice with, so it's great for live performances, etc. The large bell allows the sound to project far. Please consider this opportunity.
