Silent mute for trumpet, SB7X, with unused Personal Studio STX-2. - Brand: YAMAHA - Model Name: SB7X - Product Name: SILENT Brass - Accessories: Personal Studio STX-2 - Condition: Unused Thank you for viewing. This item was purchased by a family member on Amazon five years ago and has never been used, without even opening the box. The plastic wrap is still on as shown in the photos. I would like to pass this on to someone who will use it, rather than letting it sit unused at home. A new model has been released, and although the pickup mute model number is the same, the price has increased considerably. This item is completely unused and new, but considering it's been five years, how about pricing it around the level of a good used item? It has been stored indoors, and there are no cigarettes or pets.
