Overview

Available now is a 1980 BOSS CS-1 Compression Sustainer, Made in Japan and featuring the desirable early silver screw.

The CS-1 comes from the early era of BOSS compact pedal production and offers a simple two-control compression circuit with Level and Sustain controls, plus a Normal / Treble mode switch for changing the tonal character of the effect.

This example retains its black Made in Japan label and ACA power specification, giving it plenty of appeal for collectors chasing early Japanese BOSS pedals as well as players wanting something a little different from later compressor designs.
