Atelier Schmidt S3/4 I believe this is a wonderful mouthpiece with a deep tone and ease of control. Opening: 1.15 Facing length: Medium I previously purchased this in a near-new condition (tested only) from here and used it for about a year. Therefore, there are marks from the mouthpiece patch and ligature, as well as minor scratches. The tip of the mouthpiece is free of scratches, and I believe it can still be used for a long time.
