Price reduced! This is a Kelly mouthpiece that has been modified at a workshop. The 1-1/2 size has been slightly widened. It's the size for a bass trombone. Kelly mouthpieces don't usually have much resonance, but this one has a weighted body and a metal shank, resulting in a resonant and soft tone. It's a good option for those with metal allergies or for outdoor performances in winter. The condition is good, but as it's a modified item, there are some minor scratches.
