The pinnacle of modern trumpet mouthpieces, the Monette Resonance Prana model. This model was developed and used by the master Adam Rapa before he launched LOTUS. Comes with the original box. Equivalent to a Bach 1-1/2C inner diameter, with a semi-flat rim for endurance and stability, and a cup slightly shallower than a Bach C, this is a very well-balanced model. Compared to the latest Unity models, the Resonance Prana model is darker and closer to the generally imagined Monette tone, with a thick, airy, and soft sound. It generally produces a very thick sound, but when you blow strongly, you can easily produce a sharp, clear trumpet-like sound, which is incredibly satisfying and is a particularly outstanding feature of the Adam Rapa model. Also, the rim feel allows for a seamless transition from a standard mouthpiece. Cup Outer Diameter: 27.23mm Outside Rim Contour: Medium Cup Inner Diameter: 16.94mm Inside Rim Contour: Medium+5 Cup Depth: 1-1/2 between C and D Size Comparison: Flat Rim ＜PRANA Series＞ A mouthpiece designed with a wide backbore, particularly excellent for airflow and intonation in the high register. With the Prana model, you can achieve a wide range of expression, from a very thick and soft tone to a sharp, piercing sound, making it a wonderfully balanced model that underpins Adam Rapa's performances. This model is quite easy to play, even for those who find Monette mouthpieces difficult. High notes are also very easy to produce, making it very comfortable to play. Adam Rapa currently often plays LOTUS 2XXL and other models with a 2nd rim, but this model also has a similar feel to the LOTUS 2 series rim, and the Monette-like character is appealing compared to LOTUS. The condition is quite good, but as it is used, please assess the details from the photos and purchase with your understanding.
