"Look! Come and see the Mira's capabilities. In the Spanish language, Mira is a command that translates to look, see, and call attention to. With the Mira Optical Compressor, you’re creating and shaping a studio-grade timbre that demands to be seen, heard, and above all, felt. The Mira delivers warm, analog optical compression with mountains of sustain and a smooth attack and release that can be blended in to taste. Dynamically engage the senses with the Mira. The Mira is a true bypass optical compressor offering studio-grade sound sculpting and sustain packed with controls you’d normally only find on studio units. Use the Blend knob to mix in your compressed sound with your clean tone to maintain note clarity while offering increased sustain. Mira also offers in-depth control over Attack, Release, Ratio, and a Make-Up knob to help maintain unity levels after your signal has been compressed. For higher headroom, Mira runs internally at ±15VDC." -Walrus

This pedal is in great shape and doesn't really have many scratches throughout the enclosure. Sounds awesome! Mega versatile. Hard to beat the opti-comp sound!
