The Compressor allows for terrific sustain by cutting excess signals and boosting weak ones. This versatile unit can also be used as a limiter.


If only all boost pedals could sound this good. Using the Attack control and setting the Sustain control at a minimum volume, the SCO-1 works as a limiter as well. Using OUT 2 MELLOW, a mild sound with longer attack or direct instrument sound can be obtained. The addition of a tone control makes Arion's Stereo Compressor Boost Pedal one of the most versatile compressor pedals on the market. The SCO-1 features an easy-open battery compartment for simple 9-volt operation.
