This is a Brilhart Metal 5* for tenor saxophone. These were some of Arnold Brilhart’s first mouthpieces as indicated by the “Designed by Arnold Brilhart” on the shaft. This piece has a .091 tip opening, a high baffle, straight side walls, and a large round chamber. These are pieces that have not been appreciated as much as they deserve. For a projecting tenor sound that maintains a lot of body to it, these are in the same league as a vintage Berg (=Berg #0 baffle), and they sound surprisingly similar to a Guardala Studio or Michael Brecker piece (of all things). The far edge of the bite plate has a hairline crack. This doesn’t affect functionality though. Besides that, this piece is in excellent condition.
