The C4 4-knob Compressor has knobs for Sustain and Level just like the original two-knob version, but the Input Clipping and Attack controls are now controlled by knobs on top of the pedal rather than with trim pots inside the pedal as with the 2-knob version. This 4-knob version is perfect for high output guitars, bases, line level instruments, recording, etc.
