caption_attribution_description: Français&#160;: Pédale de chorus Boss CE-3 avec modification "Vibr'o'tone" par MSM Workshop (switch sur le côté droit). La pédale a été fabriquée au Japon en août 1984 d'après le numéro de série. En utilisant le mode stéréo II, on a d'un côté le son direct (sortie B) et de l'autre un vibrato (sortie A). Vue de dessus. English: Boss CE-3 chorus pedal made in Japan in August 1984 according to the serial number. The pedal has been modded by MSM Workshop ("Vibr'o'tone" mod, switch on the right of the pedal). When using the II stereo mode, output B gives the dry signal while output A gives a vibrato. Top view.
context_page_description: In music, a chorus effect occurs when individual sounds with approximately the same time, and very similar pitches, converge and are perceived as one. While similar sounds coming from multiple sources can occur naturally, as in the case of a choir or string orchestra, it can also be simulated using an electronic effects unit or signal processing device.
  When the effect is produced successfully, none of the constituent sounds are perceived as being out of tune. It is characteristic of sounds with a rich, shimmering quality that would be absent if the sound came from a single source. The shimmer occurs because of beating. The effect is more apparent when listening to sounds that sustain for longer periods of time.
  The chorus effect is especially easy to hear when listening to a choir or string ensemble. A choir has multiple people singing each part. A string ensemble has multiple violinists and possibly multiples of other stringed instruments.
context_section_description: Although the electronic chorus effect can be obtained by the multiple ways mentioned above, some devices have acquired a high status among musicians, especially in the "effect pedal" form.
  Boss CE-1 – Released in 1976, it was one of the first chorus effect pedals commercially available, based on the same circuit from the Roland Jazz Chorus amplifier. It was originally conceived for keyboard and synthesizer players, but guitarists have occupied it as well, like John Frusciante (Red Hot Chili Peppers).
  Boss CE-2 – A smaller pedal (in the standard Boss enclosure) than the CE-1. it was a popular choice for guitarists during the 1980s.
  Electro-Harmonix Small Clone – Used by Kurt Cobain (Nirvana).
