What Is A Compressor Pedal?
A guitar compressor pedal smooths out the audio levels of your playing by suppressing the loud parts and boosting the quiet parts. This results in a flatter, more even tone. Potential benefits of compression are: increased sustain; a louder overall tone; and a sound that potentially sits better in a mix. Over-use of compression can result in a lifeless, un-musical tone that lacks nuance and can be tiring for the listener.
