This mouthpiece is slightly smaller and shallower, making it easier to play in the high register! Schilke This is a Schilke mouthpiece, loved by players of all genres. The inner rim diameter is slightly larger than a Bach 10-1/2. The rim is flat and thick. The rim apex is slightly inward, sloping gently towards the outer edge of the rim. The outer edge of the rim is somewhat distinct, a unique Schilke rim design. The outer rim diameter feels similar to a Bach 10-1/2. This makes it soft on the mouth, comfortable even with hard pressure, and less tiring. The cup has a gentle UV shape, with a depth similar to a Bach E cup. The throat area just before the bore is slightly wider, resembling a double cup like the Stork Vacciano model. The throat is #27 (3.66mm). The backbore is similar to a Warburton 9. The inner side of the shank end, about 1.2mm, has a smooth slicing finish like a Schilke 14A4a. This mouthpiece has good response and a sharp sound, yet it resonates with a thick and full tone. Recommended for pop music, big bands, and horn sections. Also recommended for piccolo trumpet, which requires high notes, and for use in wind bands for pop music. - Model Name: Schilke 7B4 - Material: Silver-plated - Size: For Trumpet Thank you for viewing.
