It is without doubt the most free blowing and subtle mouthpiece I have ever used on this sax. I put my bell mic on and listened through headphones to what was coming out and was really impressed. I can blow just a little and get that whisper like sax sound (more like an alto or tenor). I’ve never known this level of subtlety from my soprano. The lowest notes are as simple as the mid body notes and the upper register notes come easily as well. All in all a completely satisfying acquisition. All the hype around your handmade pieces was justified. It really had to be so as you focus solely on these wonderful quirky saxophones and know them very well. Thanks very much.
