Cup Diameter
The Yamaha TR-SHEW-JAZZ has a cup diameter of 16.85 mm compared to 16.50 mm on the Denis Wick 4B — a difference of +0.35 mm. A wider cup generally produces a fuller, darker tone but requires more air support.
Cup Depth
Both mouthpieces share a medium cup depth, so the sound character from depth alone will be very similar.
Throat Diameter
The Denis Wick 4B has a wider throat (3.74 mm vs 3.65 mm). A wider throat allows more air through, increasing volume and projection but reducing resistance.
