Used Boss CS-1 - Made in Japan
This is the first Compression/Sustainer pedal released from Boss. Like all compression pedals it reduces the output of sounds over a set threshold relative to the strength of the input signal, making levels consistent and improving sustain. In the CS-1 this is done by means of photocouplers. This is a very different effect than all of Boss' later Compressor/Sustainer pedals which use VCA control. Therefore, this is a VERY special pedal.
It's by far the most musical and interesting of all of the Boss compression pedals.
This unit is the "Metal Screw" "Black Knob" "Black Label" Made in Japan model.
The CS-1 was sold from July 1978 to February 1982. This particular model dates to "October 1980".
Serial number 990x
This box is in great shape given its age, with minor dings and scratches on the housing.
