Old Blood Noise Endeavors BL-37 Reverb FX Pedal

The OBNE BL-37 Reverb is not your average ambient pedal, it’s a modulated reverb machine that blurs the lines between space, tone, and time. Part of Old Blood Noise Endeavors' boundary pushing BL series, the BL-37 combines simplicity with depth, offering a unique dual modulation architecture inside the reverb trail itself. The result? A swirling, lush atmosphere that feels more alive than algorithmic.

At the heart of the BL-37 is the Clock control, a single slider that warps the entire character of the reverb. Turn it left for a tight, tile room slapback. Push it right and you’re drifting through a lo-fi, stretched out haze, like a broken tape loop lost in space. The Feedback control adds length and modulation intensity, while Mix lets you go from fully dry to 100% wet. There’s also a Volume control to ensure perfect integration into any signal chain.

Built with a soft-touch true bypass footswitch and minimalist control set, the BL-37 is ideal for players who want deep, evolving textures without menu diving. Whether you're stacking with delays, shaping post rock textures, or just adding a touch of dreamlike wash, this is reverb with a personality all its own.

From hi-fi shimmer to warped cassette trails, the BL-37 belongs in any rig where exploration is the goal.
