I usually play on a Yamaha 16e-s gp and very happy with it. After hearing my colleage playing on this Neo mouthpiece and admiring the darker sound decided to buy one and give it a try. The quality is very good as all Yamaha products, it has a dark sound and suits British Brass Band playing, produces a lovely tone and is very good on slotting, it has a comfortable rim. Some notes seem a little flat and need lipping up, however it’s early days for me and time should sort this out. The main problem for me seems lack of power, as I play in a first section British Band and although a good section blending mouthpiece it’s easy for my sound to be drowned out. When I dep for lower section bands with less power ability, the mouthpiece comes into its own providing a lyrical pleasing sound. So in conclusion I reccomend this product to those who require a comfortable very pleasing sound in a less intense situation
