Great tenor piece! Slightly curved sidewalls, small chamber, subtle but long rollover baffle. 0.102″ tip opening. This piece has great projection but also speaks easily at low volume, with a very flexible neutral to bright tone. Much easier to play sweetly than what the tip opening suggests. The overall shape is very sleek, between a normal hard rubber and metal, so a standard hard rubber size alto ligature fits well. This is guaranteed to please! I do 5-day trials on mouthpieces too, you only pay shipping.
