Thank you for viewing. This is a YAMAHA YTR-800G. It's an early model, so the 3rd valve slide stopper is the same rod type as Bach, which is cool. It's a Schilke-type, so it responds quickly, and it's easy to control the tone. There are some minor scratches, but I don't think there are any noticeable ones. I used it for a solo performance at a concert last year. I'm selling it to declutter. Thank you.
