This is an 8335, an older generation than the Xeno. As you can see, it's quite worn. However, the tuning slides and pistons are not stuck, and it produces a proper custom sound when played. (The pistons move somewhat sluggishly) The original case and mouthpiece are included. As stated in the title, this is an as-is item. Please purchase with the understanding of its current condition. Feel free to ask any questions you may have.
