Featuring an internal trim pot for setting gain reduction up to 30dB, an easy-to-use control spread of compression and volume knobs and a bright LED indicator for easy reading, the Demeter Opto Compulator brings all the sweet sustain and compression desired in a pedal without the sacrifice in tone. Built to emulate the coveted sound of vintage studio optical compression, this pedal brings unheard clarity to notes while in solo picking and sustained warmth reminiscent of a '60s record.
