The guitarist used a flanger to create a unique sound in the song.
Flanger → The word 'flanger' originates from the term 'flange' (from Middle English *flange*, meaning a projecting flat rim or edge) combined with the suffix '-er' (meaning a person or thing that performs an action). A flanger is a device that creates a specific sound effect, often used in music, by modulating the audio signal, which can be thought of as a 'thing that flanges' the sound.
Think of a 'flange' as a part that projects or modifies something, and remember that a 'flanger' is a device that modifies sound.
