Extremely versatile, essentially 3 compressors in 1 pedal. Lighting, which gives you visual perspective of what you've set your compressor to do. Boutique feel and durable housing, as with every Darkglass product.
EDIT: No longer recommended, unfortunately. During the few years of marginal use, the pedal has been sent TWICE to Darkglass for PCB replacement due to problems. (no signal comes out) First time was free, the second time I had to pay for the PCB myself because the warranty had already expired. I've moved onto a hopefully more dependable, fully analog compressor by another manufacturer.
