Here, this will help you figure it out, and remember it. This is how I
remember what it does. Just take the word "Modulation". Here is the
definition at dictionary.com
mod·u·la·tion Pronunciation Key (mj-lshn)
n.
The act or process of modulating.
The state of being modulated.
Music.
A passing or transition from one key or tonality to another.
The result of such a transition.
A change in stress, pitch, loudness, or tone of the voice; an inflection of the voice.
An instance of such a change or an inflection.
The harmonious use of language, as in poetry or prose.
Electronics. The variation of a property of an electromagnetic wave or signal, such as its amplitude, frequency, or phase.
--------------------------------------------------------------------------------------
Ok, so a "Phaser" take the signal (your guitar sound) and runs it out of
phase with itself. That gives you that weird swishing sound.
Now add Modulation to that, or, by definition a changing of pitch or
frequency, and you have a swishing sound that also changes pitch
(like a chorus).
I hope that helps out some! Good question by the way!
