Chorus

A chorus box, in theory, adds the illusion of two instruments playing the same things at the same time. In reality, they just basically make the sound thicker and more shimmery. Kurt Cobain used one a lot.

Technically what they do is split the signal into two parts and let one pass through unaffected (the dry signal), and the other side of the signal is detuned very slightly and has a very tiny delay added to it. (This is the wet signal.)

I guess the idea is that two instruments playing together can never, by nature, be absolutely tuned identically or played in an absolutely identical rhythm. They are always off, due to the physics of making a string resonate and such, a matter of fractions of a semitone, and off in time by a millisecond or so, even when played by the most adept human players.

Chorus boxes usually have two or three knobs : chorus (amount of detuning), mix (dry-to-wet signal ratio) and sometimes some sort of tone or volume knob.

Examples: The Chase Theory: "FM Radio." Third Eye Blind: Third Eye Blind (album) (1:05 into the song "Motorcycle Drive-By" and throughout the album). Edwin McCain: "I'll Be." Smashing Pumpkins: "Sweet Sweet." Nirvana: "Come as You Are."
