The BL-44 Reverse Variable Clock from Old Blood Noise Endeavors is an experimental reverse delay that continuously plays your signal backward in real time. Instead of relying on fixed loops or static buffers, the BL-44 reacts instantly to what you play, creating evolving reverse textures that feel organic and unpredictable.

By directly manipulating the internal clock, the BL-44 allows you to stretch or compress time while simultaneously altering audio quality. Push it into fast, articulate reversals or slow it down into degraded, warped delay trails with a distinctly lo-fi edge. This clock-based design gives the BL-44 a raw, expressive character unlike conventional delay pedals.

Minimal controls keep the experience intuitive while still offering a surprising range of sonic possibilities—perfect for ambient players, experimental musicians, and anyone looking to break away from traditional delay sounds.

Highlights:

• Continuous real-time reverse delay

• Variable clock control for time and texture

• Clean to heavily degraded reverse sounds

• Compact, performance-focused design

• Part of OBNE’s Black Label experimental lineup

Power requirement: 9V DC center-negative (not included).
