Final answer:
George Harrison used a volume pedal to smoothly transition into guitar chords on his song I Need You, which added expressiveness and was a signature part of his sound.
Step-by-step explanation:
George Harrison employed a particular device to ease in the guitar chords on his song I Need You. This device is known as a volume pedal. The volume pedal allows the guitarist to change the volume of the guitar sound without using their hands, which particularly creates a smoother entrance for chords and notes.
Harrison's use of the volume pedal adds a unique expressiveness to the song, allowing for the dynamic swells that are heard on the recording. The volume pedal was an innovative tool during this time and contributed to the distinct sound of many of Harrison's songs during his time with The Beatles and his solo career.
