This instrument is heavier than our smaller-belled instruments and the lightest instrument we make with our larger 5 5/8" bell. It can be played with either our STC-2- or STC-3-weight mouthpieces, which makes it unusually versatile. Lead players or players with a naturally dark sound would usually use the lighter, STC-2-weight mouthpieces - and many jazz or symphonic players would use the heavier STC-3 weight mouthpieces, which helps produce a thicker, more stable sound. The 993 Bb was used by Wynton Marsalis for many years in the section of the Lincoln Center Jazz Orchestra and in small group jazz settings.
