Whether it was the title track to Bob Dylan’s Highway 61 Revisited or the police siren in a classic cartoon, chances are that you’ve heard Acme’s Siren Whistle without even knowing it! This little whistle is about as simple as an instrument can get — just blow into the small end — and comes with a handy ring to attach a lanyard. While it might be most famous for being featured in rock tunes and cartoons, its mock-siren tone is often used for comic effect in orchestral applications, and (more importantly) the world-famous Sweetwater kazoo band would simply be lost without it. Finally, this funny whistle’s construction is no joke: the Acme Siren Whistle is built to tradition-instrument standards with top-quality parts by a team of siren specialists in jolly old England.
