Although it wasn’t the only chorus effect around at the time, the Boss CE-2 Chorus pedal played a huge role in the popularity and predominance of this effect during this period. Several chorus effects preceded the Boss CE-2’s introduction in late 1979. Roland’s Jazz Chorus series amps whetted many guitarists’ appetites for the chorus effect, but most players didn’t want to be limited to a particular amp just to use the effect. Featuring only Rate and Depth controls, the CE-2 is basically “idiot proof” and provides great-sounding chorus effects no matter where the knobs are set. Pretty much everyone who used chorus during the ’80s had a Boss CE-2 at some point or another.
