2.7 Distortion effects and amp simulations
VOCAL DISTORTION: This effect is very hip when used on vocals and drum loops, and is combined with a
delay and flanger.
TUBE DISTORTION: This effect simulates the sound of different tube types. When an analog tube, as found in
a guitar amplifier, is overamplified by raising the input signal (e.g. of a guitar), the original signal is mixed with
the harmonic overtones. With rising overmodulation (also known as saturation of tubes), the original signal is
distorted and the sound is fresh and full. This is a classic sound in rock music.
GUITAR AMP: This effect simulates the sound characteristics of a complete guitar amplifier. You can connect
a guitar or bass (after appropriate pre-amplification) directly to the VIRTUALIZER PRO, and from there to a
mixing console or recording device.
FUZZ: This is a special guitar distortion type. Jimi Hendrix was one of the first guitarists to recognize the
appeal of this broadband transistor overmodulation. The humming distortion of the FUZZ BOX has again
become popular with alternative rock and grunge. The VIRTUALIZER PRO’s fuzz works in three different
frequency bands.
SPEAKER SIMULATION: The VIRTUALIZER PRO is able to simulate various types of speakers. Typical
guitar amplifying speakers as well as multimedia speakers are available. You can also use a parametric
equalizer to further refine the sound.
RING MODULATOR: This effect allows a radical alienation of audio signals. Similar to the principle of FM
radio, the signal is multiplied by a carrier frequency, so that frequency modulation (FM) takes place. This effect
is very well suited for vocal alienation (robot voice).
LO-FI: For years, digital technique has been striving for high quality, low noise, and brilliant sounds. In the
recent past there have been increasing calls for a return “to the roots” to achieve the warmth of the old analog
sounds. The techno/dance group swears by vinyl and some music lovers miss the charm of good old vinyl
discs and tape machines. This trend is known as Lo-Fi (instead of Hi-Fi). We have taken this tendency into
account and included the relevant effect in the DSP2024P. Your recordings sound like 8-bit audio, complete
with noise and humming like the old days! A true drum loop in TR808/TR909 style really gets going when it
sounds thick and dusty.
