For sale is an Edwards Duo Bore bass trombone slide. Excellent slide action, no wear to tubes, professionally used no repairs ever done or needed. Minor lacquer wear from use, please see photos. Brass outer slide no heavy nickel oversleeves. This is a stock lightweight Edwards duo bore bass slide, bore is .562-.578. sold with one lead pipe. Shipped in a slide doctor case. fits Eward's bass trombones, of course. But i used it on a Bach Bass trombone bell section, and on a Yamaha YBL613H bell section. I've also tried it on a Shires bass bell section, and though the tenon fits, the nut does not fit as well. This is a great slide and you can save a lot over a new one if you don't mind a little normal finish wear. Thank you
