Adjusted and fully functional. Good airtightness. Piston work is smooth. All slides are smooth. Originally thought to be a Taiwanese-made instrument, it has been customized in various places, such as a satin-like finish and slides. The braces have also been changed to a detachable type. Please check the condition before purchasing. The impression is a vintage feel, dry, core sound, and well-rounded tone. Intonation, sound quality, and playability are not a problem. Enjoy the vintage customization. - Included accessories: mouthpiece Bach 10 1/2 C, CC Shiny case with strap (originally red, but repainted black). No damage, in good condition. Thank you for viewing.
