Old Blood Noise Endeavors BL-37 Reverb Variable Clock Effector Pedal – New

The Old Blood Noise Endeavors BL-37 is an experimental reverb from OBNE’s Black Label (BL) series, designed to create constantly shifting, otherworldly spaces through clock manipulation. Unlike traditional reverbs, the BL-37 applies modulation at two separate points within the reverb trail, resulting in a lush, wandering ambience that feels alive and unstable in the best way.

At the heart of the BL-37 is the Clock slider, which dramatically reshapes both time and texture. Slide it toward faster settings for short, reflective “tile bathroom” echoes, or slow it down to stretch the reverb into dark, smeared, lo-fi atmospheres that feel completely detached from physical space. The simplified control layout keeps the experience immediate while still offering deep, expressive range.

The BL-37 excels at ambient sound design, experimental textures, and evolving washes that reward subtle movement and performance interaction.

Features:

• Experimental reverb from OBNE’s BL (Black Label) series
• Dual modulation points within the reverb trail
• Variable clock control for time and texture
• Ranges from tight, reflective echoes to dark, lo-fi reverb
• Simplified, performance-focused control layout

Requires 9V DC center-negative power (power supply not included).
