Tony Banks was known for his innovative and expressive keyboard playing, and his keyboard setup during the 1975 tour with Genesis reflected this. He used a variety of electronic instruments to create a wide range of sounds and textures, including a Mellotron M400, a Hammond T-102 organ with a Leslie speaker, and an RMI 368x Electra Piano and Harpsichord.

The Mellotron M400 was an early type of sampler that played back recorded sounds on strips of magnetic tape. It was known for its distinctive, otherworldly sound and was often used to create lush, string-like textures.

The Hammond T-102 organ was a portable instrument that was known for its warm, expressive sound. It was often used by musicians in a variety of genres, including rock, jazz, and blues.

The RMI 368x Electra Piano and Harpsichord was a hybrid electronic instrument that combined the sounds of a piano, harpsichord, and electric organ. It was known for its bright and punchy sound, and was often used by musicians in the 1970s for its versatility and portability.

Together, these instruments allowed Tony Banks to create a wide range of sounds and textures, and helped to define the signature sound of Genesis. His keyboard setup during the 1975 tour was an essential part of the band's live sound and helped to make their concerts a truly memorable experience for fans.
