BL-37 is a reverb pedal within OBNEs BL line. It features modulation at two points in the reverb trail to give a wandering, lush reverb unlike any of OBNEs other reverbs, with a simplified control set. The Clock slider is the key to its magic, moving from a quick, tile-bathroom echo out to a dark, lo-fi-stretched reverb, unlike any space in existence. Soft-touch bypass footswitch for true bypass and minimal switch noise. Requires 9V DC center negative 2.1mm jack power supply capable of 110mA (not included). The art of BL-37 is by Brandy M. Patterson.
