Laskey Tuba Mouthpiece Cup Descriptions:
Cup B – A deeper bowl than Cup G. Wonderful bottom to the sound.
Cup H – Relatively straight sides that blend into a concave funnel as it enters the throat (Helleberg).
Cup G – Produces more briiliant sound than the H model and works well on rotary valve tubas (Geib).
Cup F – Like the Helleberg cup in shape but approximately 1/3 more shallow.
Cup C – Moderately shallow bowl cup. Ideal for solo performances on Eb and F tubas.
