3 Distortion
You can use Distortion effects to recreate the sound of analog
or digital distortion, and to radically transform your audio.
Distortion effects simulate the distortion created by vacuum tubes, transistors, or
digital circuits. Vacuum tubes were used in audio amplifiers before the development of
digital audio technology, and are still used in musical instrument amps today. When
overdriven, they produce a type of distortion which many people find musically
pleasing, and which has become a familiar part of the sound of rock and pop music.
Analog tube distortion adds a distinctive warmth and bite to the signal.
There are also distortion effects which intentionally cause clipping and digital
distortion of the signal. These can be used to modify vocal, music, and other tracks to
produce an intense, unnatural effect, or for creating sound effects.
Distortion effects include parameters for tone, which let you shape the way the
distortion alters the signal (often as a frequency-based filter), and for gain, which let
you control how much the distortion alters the output level of the signal.
The following sections describe the individual effects included with Logic Express.

Warning: When set to high output levels, distortion effects can damage your hearing
(and speakers). When adjusting effect settings, it is recommended that you lower the
output level of the track, and raise the level gradually when you are finished.
