The YCL‑450M (also known as the “Duet+” version) is an intermediate-level Bb clarinet that merges traditional craftsmanship with advanced technology. It features a grenadilla wood body with an ABS resin–injected upper joint bore and tone holes, designed to protect against moisture, reduce cracking, and enhance long-term stability and intonation. This innovation results in an instrument that’s highly responsive, even with less air pressure—making it accessible for younger or developing players. The refinements in the barrel, bell, and register vent tube contribute to better projection, improved pitch accuracy, and improved performance across the registers.
