Throat #2

This throat length is 3/16". It has an efficient blow with a bit more resistance and a bit smaller slot. This also brightens up the sound a bit.

Throat #3

This throat length is 1/4". It has a tighter blow with more resistance and a smaller slot. This also adds more sizzle to the sound.

Backbore #3

This is our middle of the road backbore. It is amazingly versatile. All adjustments for blow, slot, and sound are done much more efficiently with cup and throat combinations.
