Large shank trombone mouthpiece for the advanced player.
• 25.50mm (1.004 inch) cup diameter.
• Deep "E" cup.
• 0.283" throat.
• Compares to a Bach 5, 5G or 6 in diameter.
• Equivalent to Greg Black "0.25."
"Leaving the rim and cup diameter exactly the same [as the 7C] and only adjusting the throat and cup volume (depth) makes a lot of sense. This mouthpiece is used on works that require a larger width of sound in all sound registers." -Griego
