ARBITER FUZZ FACE
The Beatles had been fans of distortion since the making of their second album, With The Beatles, in 1963. They experimented with a Maestro Fuzz-Tone during the recording of “She Loves You” and “Don’t Bother Me”, and in 1965 McCartney ran his bass through a Tone Bender for the recording of “Think For Yourself”. It’s not known when the Arbiter Fuzz-Face entered the Beatles’ world, but Harrison is seen using one in photos from the Twickenham sessions.
