The original zoom barrel design on which all others attempted to copy - this is the only one that won’t leave a gap when zoomed out so your throat tones stay proportionate to the rest of the instrument.

Zooms from 64-67 mm, tapered bore.

Some marks on the ring, but turns freely and doesn’t affect sound.

Delrin upper and bore, wood bottom. I like the stability and warmth of a synthetic bore.
