I recently inquired about a Charlie Allen mouthpiece up for sale. Unfortunately, the seller lost the mouthpiece while moving (temporarily hopefully). I was interested in these mouthpieces because they were played by greats like Eldridge, Cat Anderson, and (from what I understand), the horns in Count Basie's orchestra. Therefore, I thought they might be quality pieces worth looking into, but has anyone ever tried one before? What are your opinions on them?
