BEST BRASS / BTB-1A GP

A bass trombone mouthpiece from BEST BRASS. It features a rich tone suitable for large brass bands and orchestras. Gold-plated finish.

BEST BRASS's proprietary multi-length system achieves stable pitch regardless of the size or depth of the cup. You can get a sound that makes your instrument sound like it's been upgraded. It will also solve problems such as difficulty in producing high tones and wobbling low tones.

[Features of the Groove Series]

■Multi-length system
With a typical mouthpiece, the overall length remains the same even if the cup size changes, so there is variation in the sense of pitch. With BEST BRASS, the shallower the cup, the longer the overall length, and the deeper the cup, the shorter the overall length. As a result, you can get accurate pitch and efficient resonance.

■Groove processing
It efficiently vibrates your lips, solving problems such as difficulty in producing high tones and wobbling low tones. As a result, you will not get tired easily while playing.
