This is a rare, original Dave Guardala Studio model mouthpiece for the alto sax. Finding these pieces in original form for the tenor sax is hard enough, finding them for alto is almost unheard of. This piece shows a couple little nicks around the tip, as seen in the photos, but it still plays well, so for the sake of being original we have left it alone. It is stamped SAG (Studio Alto Gold), with serial number 27317, and measures about .095”. It shows minor finish wear around its body but nothing significant, and only a single small tooth mark in the original pink bite plate.
