Soulo Mute's Aluminum Trumpet Straight Mute is endorsed by some of the top classical, commercial and jazz musicians in USA and Europe as the best straight mute on the market. | Perfect Pitch, Free-blowing experience and excellent projection are all a result of our new patented breakthrough aerodynamic design, which allows the air to flow unobstructed inside and outside of the mute. There is no crimp connection where the top and bottom parts of the mute meet together. | This is the only straight mute with a full hemisphere on the bottom, flanked by an aluminum ring that acts as a base so the mute can stand upright. Other straight mutes are simply spun with a resulting flat surface, which causes the mute to back up and resist the air you put behind it. We only use the highest quality aluminum, which offers a brilliant sound and makes it perfect for classical and orchestral playing and big-band performances | Extremely lightweight, only 2.4 oz! Neoprene enhanced cork outperform natural cork and don't wear down as fast. Our corks lock the mute in the bell thanks to our machine tapered radii on the inner surface of the corks. | Soulo Trumpet Straight Mute makes a perfect gift for any trumpet player for any occasion - birthday, Christmas, graduation etc.
