Thank you for viewing. This is a Bach bass trombone 50B3GO for sale. While it shows signs of use, there are no major scratches or dents, making it an instrument ready for immediate use. Many 50B trombones in circulation are made of yellow brass, but I believe that gold brass truly suits a bass trombone's sound. The low notes produced with a large mouthpiece on this instrument are so powerful, they could almost take on a full orchestra by themselves (lol). I'm sad to let it go, but as I don't have many opportunities to play it, I'd like to pass it on to someone who will cherish it. The original case is included. Please consider it. m(._.)m
