Bass pedals are an electronic musical instrument with foot-operated pedal keyboard with a range of one or more octaves. The earliest bass pedals from the 1970s consisted of a pedalboard and analog synthesizer tone generation circuitry packaged together as a unit. Since the 1990s, bass pedals are usually MIDI controllers, which have to be connected to a MIDI-compatible computer, electronic keyboard, or voice module to produce musical tones.
Bass pedals serve the same function as the pedalboard on a pipe organ or an electric organ, and usually produce sounds in the bass range. Bass pedals are used by keyboard players as an adjunct to their full-range manual keyboards, by performers of other instruments (e.g., electric bass or electric guitar), or by themselves.
Pedalboards have been a standard feature on pipe organs for centuries, and since the 1930s, electromechanical organs such as the Hammond organ often included pedalboards. As electronic organs became more compact and portable in the 1970s, some manufacturers began building pedals that could function separately from the organ console. These afforded the player great portability, and flexibility in combining them with other instruments and electronic equipment.
An early and very popular bass pedal device was the Moog Taurus. Moog called this instrument a "Pedal Synthesizer" in their literature, and explicitly pointed out that its five-octave range made it "more than a bass instrument". [1]. Despite these efforts, most players used them for basslines, and the term bass pedals stuck. The Taurus I and II models are no longer in production, but they are prized as vintage instruments. In 2010, Moog introduced a new model, the Taurus III, in a limited run of 1000 units.
Several progressive rock and hard rock groups (such as Yes, Genesis, Led Zeppelin and Rush) and alternative rock groups such as U2 and The Police used bass pedals. Often, the group's bass guitarist would play in a standing position, meaning that they could only use one foot at a time to play, rather than play sitting down with both feet, as organists traditionally had. However, John Paul Jones of Led Zeppelin used bass pedals while sitting down at a keyboard. Bass guitarists frequently used Taurus pedals to hold down sustained, low-pitched pedal points while performing high-register melodic lines or percussive parts on the bass guitar. In 1983, Phil Collins' song "I Don't Care Anymore" featured Taurus pedals, unusually played by hand. Bassist Mo Foster appears in the music video as the man behind the machine.
