The RS-Classic has this typical horse-shoe shaped chamber It determines the sound of this mouthpiece. Great balance and projection that fits all combinations of classical settings. Altissimo’s are easy and subs are a breeze! Complete with our standard RS Ligature, but also available in combination with our great ligature, the Spiro! We design and produce all of our mouthpieces ourselves and range from 3D printed to resin to metal mouthpieces.
