- controls how fast the compression drops in after the start of a volume peak
- controls how long the compression is applied after a volume peak
- controls the tone (bass/treble?)
- controls the amount of compression?
The BC-04 is designed to improve and refine the sound of a bass-guitar. It extends the instrument's sustain and compensates the volume of different notes, making fast solo-passages clearer and more precise. At certain settings the BC-04 works as a limiter to prevent signal-overloads, which is especially useful for the slapping technique.
