Model RT-50 is the largest funnel-shaped style in the current line. The sharp inner rim aids articulation and tonal clarity in this well-above-average cup volume. This model provides huge dynamic range and fast response. It aids low register playing while still providing a good upper range. It is recommended for advanced players who prefer a truly large mouthpiece. Available in three versions; Standard, heavy shell RT-50+, and L (intermediate weight-special order only).
