Yamaha Duet Intermediate Wooden Clarinet - YCL450NM-USED

Yamaha Duet Intermediate Wooden Clarinet - YCL450NM-USED

The USED Yamaha YCL-450NM intermediate clarinet is in great shape and offers a surprisingly professional sound with an easy response. The bell shape and barrel design are similar to that of the V Series. This new bell design gives improved intonation and projection, especially in the all-important lower register, while the new barrel enhances the 450's response, flexibility, and tonal focus.

The YCL450NM features a unique manufacturing process that provides the added benefit of durability to the clarinet. Using patented technology, the injection-molded inner bore is designed to resist cracking while also stabilizing the bore which adds consistency and durability.

The upper joint body is drilled out slightly larger around the bore and tone-holes. Thermoplastic ABS resin is injected into the cavity, instantly forming the inner shape of a clarinet. It is designed to preserve as much as 90% of the wooden portion, while its natural appearance is hardly distinguishable from conventional all-wooden models.

New 65mm barrel
The YCL-450NM intermediate clarinet incorporates some of the distinct qualities of Yamaha's professional and custom clarinets. One of these features is a 65mm barrel design that produces a focused tone and quick response. Players looking to "step up" their performance will do just that with this instrument.

New bell design
Nothing can be more frustrating than an unfocused, out-of-tune tone. A new resonance chamber in the bell of the YCL-450NM aids in projection and improves intonation in lower notes, allowing for consistency and confidence.

Blue steel springs
Intermediate instruments need to feel different than student model instruments. Part of making the YCL-450NM feel better is the upgrade in spring material. Blue steel springs give the keys a lighter touch and feel while producing a smooth, quick action.

Sculptured, nickel-plated keys
The nickel-plated keys provide a more clear and focused tone. Also, the nickel-plated keys of the YCL-450NM provide a good alternative for people who have an allergic reaction to silver-plating. In order to make the keys to the appropriate strength level, a technique called power forging is used. The results of this hi-tech process are keys that are exceptionally durable and contoured to the best possible ergonomic shape.

Straight tone holes with tapered undercut
Yamaha intermediate model instruments set themselves aside with their use of professional materials and features. Straight tone holes with tapered undercuts provide outstanding intonation and response making the YCL-450NM play like a pro-model instrument.
