Thunderer by name, Thunderer by nature! The Acme Thunderer is a favourite amongst the football community. With its big sound and deep tone, the Acme Thunderer gets your attention but is still considered by many to be one of the more user-friendly whistles. The Acme Thunderer is a pea whistle and solid brass with nickel plating. The Thunderer also has a tapered mouthpiece which is favoured by many users. At Clubline Football, we think the Acme Thunderer is a great choice of whistle. Good in your hand, the Thunderer looks and performs in a way that, quite simply, feels right!
