Super rare early Brilhart Tonalin Streamline ‘Designed By’ Brilhart Tenor Saxophone Mouthpiece. Medium-large tall but narrow Brilhart Tonalin chamber, straight sidewalls, very subtle rollover baffle. The worn bite plate indicates that it was well-loved. With a bit harder than my normal reed, this piece produces lovely subtones at full volume. A nice fat tone, good projection. This streamline shape works well with a normal HR alto ligature, or with the Echo Master hard rubber alto ligature on this site.
