Runyon Model 22
Alto Mouthpiece

$27.50

These mouthpieces are $33 retail at the Runyon website
These are great mouthpieces at a great price, made by Runyon for a half century or more.

They have wide side rails which combined with the facing curve, make them easy to play.

I've got these in both #5 (.073") and #6 (.077") tip openings.
I chose to get these in White, though I do have a #5 in "clear".
Charlie Parker played a white Model 22 with an .069 tip and a Rico #3 reed, which then was labeled Symmetricut.
If you've got a yen, I've got some Symmetricut alto 3.5 reeds in unopened boxes.
Perhaps the least expensive reeds you'll find.

The #5 is slightly larger and the #6 is more suited to modern tastes...you could use a softer reed with it.
