The Perantucci PT-40 is a revolution for large-bore rotary-valve F-tubas. The cup diameter of 32.00 mm is the same as that of our proven models such as the PT-64 and PT-65. In contrast, the cup is deep and elongated, with a mild transition into the throat. The rim is narrow, with a clearly pronounced inner edge. The throat bore, 8.7 Mm, is exceptional for an F-tuba mouthpiece. The result is a amazingly full and resonant sound, a particularly good low register, balanced intonation and easy high register.
