Laskey Alessi Signature Model SP For 55LS Large Shank Similar in size to a Bach 6 1/2, but with a wider and deeper cup, allowing for a full breath. I think it would be a great match for Getzen, Edwards, Shires, etc. There are some minor scratches, but it is in beautiful condition with no issues affecting performance. However, please understand that this is a used item before purchasing. - Brand: Laskey - Model: Alessi Signature Mouthpiece - Size: 55SY 55 Symphony Rim: 25.5 Throat: 7.16 Cup: Mid-Deep
