What Kind Of Effects Are There?

Contributor: TC Staff    Rating: 4/5    Views: 1045

Effects are usually based on some facet of the human ear''s abilities to figure out from amplitude and frequency content variations what a sound source is doing. This was critical when the sound source might be a saber toothed tiger. Now it is a means for us to express ourselves musically by directly invoking emotion.

I tried to count up all of the things I could think of that an effect could even possibly be based on. The raw list is stated first, just as a reference, and afterwards I give a short definition of each effect. Since distortion is perhaps the most musically interesting effect to a guitarist, I also include a primer on distortion and an exhausting ...er... exhaustive (to me at least) list of ways to get musically useful distortion in the Distortion 101 section.

AMPLITUDE BASED EFFECTS
based on the instantaneous loudness of the signal, how it changes, and how quickly it changes.

Volume control
Tremolo
Auto tremolo
Panning/ping-pong
Gating/repeat percussion
Compression
Expansion
Asymmetric comp/peak compr.
Noise gating
Attack delay
ADSR
Limiting
Auto swell

WAVEFORM DISTORTION EFFECTS
All the generic ways to distort the waveform that comes from the guitar.

Symmetrical clipping
Asymmetrical clipping
Infinite limiting
Half wave rectification
Full wave rectification
Arbitrary waveform generation

FILTER/FREQUENCY RESPONSE EFFECTS
EQ/tone controls
Treble/mid/bass boost
Cabinet simulation
Resonator
Wah
Auto wah
Tremolo-wah
"vibrato"
Phase shifting

TIME DELAY EFFECTS
Reverb
Echo
True vibrato
Flanging
Chorus/ADT
Slapback echo
Reverse echo/reverb
Sampling?

OTHER MISCELLANEOUS EFFECTS
Octave division (octave down)
Harmony generation
Phase lock tracking
Noise addition
Talk box
Voice tracking (vocoder)
Ring modulation (DSBSC generation)
SSBSC generation

COMMON COMBINATIONS
Leslie
Aphex
Enhancers
