ARP Pro Soloist

The ARP Pro Soloist is an analog monophonic synthesizer introduced by ARP Instruments in 1972 as a portable and easy-to-use instrument, designed to sit on top of a grand piano or organ. It had 30 presets to select from, such as "Fuzz Guitar", "Brass", "Flute" and many more, and other features like portamentos, growl, wow & vibrato.

Tony Banks was famous for using an ARP Pro Soloist with Genesis, which he played since Selling England By The Pound in 1973. However, Tony would swap the Pro Soloist with the ARP 2600 on the ...And Then There Were Three tour in 1978 after effectively hitting a dead end with it and its limited sonic capabilities (from its simple single-oscillator design).
