The Old Blood Noise Endeavors BL-37 Reverb Variable-Clock Effector is a modulated reverb pedal with a streamlined control set that is fast and degraded-sounding. OBNE’s goal is to create innovative designs that help musicians explore unheard sounds, and the BL-37 furthers that mission by offering a unique, glitchy reverb voice.

The BL-37 is the fastest and most ambient reverb pedal Old Blood Noise Endeavors carries in their lineup. Thanks to the pedal’s Clock slider which controls the timing of the entire system, you can easily change the speed of the reverb effect. The BL-37 can be immediate and reflective of your playing, or slow, stretchy and subtle.

The main Feedback knob controls the intensity of the effect. When added, the Feedback knob lengthens the reverb tails and creates a rise and fall to the modulation. The Mix control sets the dry/wet mix of the effect, and the Volume knob controls the overall volume of the unit.

Standard 1/4” ins and outs are accompanied by the 9V DC power supply on the side of the unit, neatly tucked under the input jack for cleaner cable management while chaining pedals. The BL-37 can also be engaged or bypassed via the soft-touch footswitch.

The BL-37’s beautiful design is a photographed portion of a painting created by Brandy M. Patterson, a New Hampshire-based artist.
