How Compression effect works.

A sound engineer would refer to threshold,attack, hold and sustain setting plus variable compression ratio which can be found in a professional recording studio compressor. Generally a guitar compressor only acts as limiter i.e. when a guitar signal reach a certain volume level / threshold, compressor would resist the signal not get stronger.

Compression effect is a dynamic effect i.e. related to volume. It reduce hard sound and boost soft sound hence it narrows the guitar sound dynamic and sounds smoother in a complete band sound mix. Most of the sound we hear in a music record has compression effect in certain level.
Compression is frequently used to tighten rhythm guitar play, increase sustain at lead and accentuate electric guitar picking.


Time needed for compressor to start work.
Slow attack setting make early picking sound of a note be heard clearer hence creating a more natural sound.
Fast attack setting would flung initial volume, crating a compressed sound.

Following are typical knobs of a compressor.


Compressor tends to reduce a guitar treble sound so a tone regulator is included to compensate this tendency.


This is to regulate adequate guitar signal strength before compressor starts to work and how the response when your guitar note disappears.

Volume aka output/gain/level
Compression process may alter incoming signal volume drastically hence compressor always enclose a main volume knob.

Compression make longer sustain on your guitar sound which is not noticeable at pop or rock music fast guitar playing. Compressor usage make a significant difference at inital tone played. A proper attack time plus compression/threshold setting the inital tone volume level to get lower hence a more professional smoother full guitar sound is produced.
When compressor is used before distortion pedal it creates a wide and fat rock guitar sound with a lot of sustain. With clean chords compressor produce a longer and fuller sounds. To simulate the specific Nashville Telecaster sound, country music players use directly connected compressor to valve amp. Compressor may enforce muted picking funk and reggae techniques as this efect prevent guitar sound to drown in a band.
