Leading Tone Whistle in D

Expensive but worth it. made of lightweight almost indestructible material. Easy to play, quality in terms of tone, volume, and timbre. Effortless transitions between octaves. Does not let you overblow, or have notes crack. Quality of sound is good and consistent even at the end of a long phrase when you are almost out of breath, or when playing highest or lowest notes. .

If you like the Clarke Sweetone, you might be the target demographic for this whistle. It takes a bit more force to blow, and it's a bit breathy, but it's got a less tinny, more solid and woodsy tone due to it's thicker, carbon fiber walls. It's also a very snappy player. I never use the extra hole, but it's probably useful for someone.
