Beginning life as the `Cyclists Road Clearer’ in the 1880s, this amazing sound effect is now part of every percussionist’s kitbag.

A real whoosh of sound, the only whistle that sings on, even when the blowing has stopped!

This unmistakable sound still finds numerous uses. From tribal dances to marine signaling, this complex whistle, made with a watchmaker’s precision, was the beginning of the ACME range of orchestral whistles and musical sound effects that remain popular to this day.
