This is a Yamaha tenor-bass trombone! It's a so-called "red bell" with a high copper content, giving it a very warm sound. It's also known as gold brass. This instrument blends well in ensembles, contributing to the overall balance and harmony. It's a representative Yamaha model that has been used for a long time in wind bands and orchestras. There are some scratches and lacquer wear, but there are no major dents, and it's comfortable to play. The slide and other tubes have been maintained, so they move smoothly and are ready to play! By the way, the entire instrument, including the inside of the tubes, has been cleaned, so you can play it immediately upon arrival. Please refrain from purchasing if you are looking for the quality and feel of a new instrument! A stand and an okura mute are included.
