I was already in love with the warm, centred contained ringing tone, great intonation and projection of the JodyJazz HR* Soprano, and the JodyJazz Custom Dark version is even better. It adds a broader, warmer, slightly grainier glow to the tone.  I never thought anything could be more beautiful than my lovely HR*.  I’m going to keep both in my case, just so I can enjoy two gorgeous beauties.  This mouthpiece will be of immense benefit of those who need to “tame” their Soprano!
