Boss CS-3 Compression Sustainer Pedal


The Boss CS-3 is supreme compressor pedal that offers several indispensable for guitarists, pedal enthusiasts, and sound designers alike. With the Compression Ratio cranked, users can achieve a nearly limitless sustain. Conversely, cranking the Sustain knob renders changes in attack more apparent. Speaking of controls, the CS-3 features an intuitive front panel design with controls for Attack, Sustain, Tone, and Level, all of which make dialing in the perfect amount of compression painstakingly simple.
