Function knobs：
SUSTAIN: Adjusts the compression ratio and increases SUSTAIN. This is the main control of your compression effect. This will limit or "squash" your signal the harder you play. As your signal decays it will increase volume to create longer sustain. NOTE: Higher sustain settings will lead to noise when not paying.
ATACK: Adjusts how fast the compressor recovers from louder signals. Faster attack times (right) benefit players using higher output instruments with active or hum bucking pickups. Turn left when using lower output pickups for nice compression bloom.
LEVEL: Adjusts the final output level of the compressor. Set to unity to compensate for gain lost from compression Or turn it up higher for a boost effect.
CLIPPING: This control limits the amount of signal going to your compressor. Leave it all the way up (full right) unless you have a need for it. If your compressor produces distortion due to a higher output level from your instrument. Or your compressor is over aggressive in compression. This control can be useful.
