With the same elegant exterior as the Arnold Jacobs Heritage mouthpiece the Canadian Brass Model MB‑83 is an easy to use, "Instant Access" mouthpiece. There are reasons: they are not overly large yet produce sound which has strong fundamental. The upper register is secure (fundamental lock-in and not dancing about on overtones).
Cup Diameter: 32 mm diameter. Long V-shaped funnel.
Rim width 7.5 mm. Moderately round with clearly pronounced inner edge.
Bore : 8.5 mm.
The Canadian Brass MB‑83 offers players who prefer a medium width cup a distinct but dark sound. The inner rim provides quick response which is comfortable and flowing in all registers. The MB-83 is designed for use with CC and BBb tubas, works particularly well on medium-bore instruments.
