The PRANA mouthpieces have a completely new design that was achieved after three years and a series of variants of developed prototypes.
Resonance mouthpieces are made in both CLASSIC and PRANA configurations and are specific for keys; made for B and C instruments.
The PRANA version is the best and it looks more like a high performance sport driving! Homogeneous sound, with a more resonant mix of overtones. They have a perfect mix of bass, midrange and treble.
