Based on Caline CP-71 6 BAND EQ+CP-16 Mark 4 Distortion
 
The Left side: EQ side: Caline CP-71 6 Band EQ covers all the essential guitar frequencies.
Each band delivers a range of ±18dB to help you find your favorite tone. The LEVEL knob controls the overall volume. The frequency bands: 100Hz, 200Hz, 400Hz, 800Hz, 1.6kHz and 3.2kHz.
 
The right side Distortion:  A great sounding distortion pedal which replicates that Mark 4 tone. The two gain controls control the high and low levels of distortion. You can also get a larger range of tones if you have a way to manipulate the mids (such as on your amp or EQ pedal). The pedal is durably constructed with its metal enclosure, is True Bypass design, and works off either a 9v battery or power supply. Note - if you're after that real Mark 4 sound this pedal should be used with a tube amp.
 
Gain1" knob: use to increases treble distortion,and adjust to the former level of distortion.
•"Gain2" knob:controls the amount of bass distortion, and adjust to the saturation level of distortion.
•"LEVEL" knob：adjust the output level.
