Monophonic attachment keyboard instrument, intended to accompany the pianos with lead voice of organ and orchestral sound. It consists of two units — a 3-octave mini keyboard attaching under the piano keyboard, and a tone cabinet including electronic sound generator, amplifier and loudspeaker.^[42] The sound generator is based on a vacuum tube oscillator and octave divider circuits originally designed for Novachord. There are three minor changed models:^[41]

• Model J (1940–1946)
• Model K (1946–1948)
• Model L (1948–1950)

Solo Pedal Unit (or Pedal Solo Unit) provides a monophonic bright bass sound on RT series and model D-100 consoles, layered with traditional polyphonic tonewheel pedal sound. Although Solo Pedal Unit is highest-note priority and it can play only one note at a time, the players can play polyphonic bass lines by the help of traditional pedal sound. The sound generator is electrically similar to Solovox Model L. It consists of a vacuum tube oscillator and five frequency divider circuits, controlled by a volume and 8-stop tablets (Bourdon 32', Bombarde 32', 16', 8', 4', 2' & 1', mute, pedal solo on) placed on the right side of lower manual. Although there are five revisions of units, these are interchangeable on all RT series consoles.^[43]
