The Theo Wanne GAIA 4 Tenor Mouthpiece was built to outplay any vintage or new Otto Link style mouthpiece. The GAIA 4 takes the huge, warm and free sound of the GAIA mouthpiece to a whole new level with greatly increased projection and flexibility. The GAIA 4 lends itself well to a traditional Jazz taste, but is at home in any style. It comes in a unique thin-body premium hard rubber which has mazing vibratory qualities and features a medium roll-over Shark Gill baffle, precision-sculpted inner sidewalls and a True-Large-Chamber which is similar to the vintage mouthpieces of the 1940s but more evolved in design. A beautiful leatherette case is included for storage and protection.
