The first use of pedals on a pipe organ grew out of the need to hold bass drone notes, to support the polyphonic musical styles that predominated in the Renaissance. Indeed, the term pedal point, which refers to a prolonged bass tone under changing upper harmonies, derives from the use of the organ pedalboard to hold sustained bass notes. [2]
Many ratchet swell devices were replaced by the more advanced balanced pedal because it allows the enclosure to be left at any point, without having to keep a foot on the lever. In addition, an organ may have a crescendo pedal, which would be found to the right of any expression pedals, and similarly balanced. Applying the crescendo pedal will ...

The clutch pedal controls the pressure plate (clutch engaged – the clutch pedal is not being pressed) or not connected to the engine (clutch disengaged – the clutch pedal is being pressed down). When the engine is running and the clutch is engaged (i.e., clutch pedal up), the flywheel spins the clutch pressure plate and hence the transmission.
By using a looper pedal, a singer-guitarist in a one person band can play the backing chords (or riffs) to a song, loop them with the pedal, and then sing and do a guitar solo over the chords. Some units allow a performer to layer multiple loops, enabling the performer to create the effect of a full band. [109]
The effect (now named Uni-Vibe) was modified to have easier access to its fuse, and a speed control foot pedal was added. It was later released in North America by Univox in 1968. [1] [3] It is commonly thought the Uni-Vibe is intended to emulate the "Doppler sound" of a Leslie speaker. However Fumio Mieda revealed in an interview the effect ...
A typical ETC system consists of three major components: (i) an accelerator pedal module (ideally with two or more independent sensors), (ii) a throttle valve that can be opened and closed by an electric motor (sometimes referred to as an electric or electronic throttle body (ETB)), and (iii) a powertrain or engine control module (PCM or ECM).
