The SilveStar is avalable in both alto and tenor. The 20 Years Edition SX90R features a sterling silver neck, nickel-plated brass body, silver-plated bell and bow, silver-plated keywork, black pads, black mother of pearl finger inlays, and a ligature designed by C. Heftrig. It has a special "Edition 20 Years" and comes with a custom case. In the 20 years of the Keilwerth SX90R series also are 20 years of pleased players, like Mike Smith (USA), “[That] powerful, warm, and balanced sound has been with me for almost 20 years, [all] thanks to Keilwerth."   Ernie Watts says, "My Shadow is the finest horn I have ever played."
