Model PT 66 is a traditional, German style mouthpiece giving a clear and lively sound. It’s deeper cup provides more volume with a slightly mellower quality than models PT 64 or PT-65.
It is highly recommended for the F and Eb tubas, but is also useful or for the CC and BBb tubas where quick response and a clear, vibrant sound is desired.
