The BL-37 Reverb Variable-Clock Effector by Old Blood Noise Endeavors is a unique and versatile reverb pedal that offers a new sonic voice with a streamlined control set. Here are the key features and specifications:

BL-37 Reverb Variable-Clock Effector Features:

  • Unique Modulated Reverb: The BL-37 is designed as a modulated reverb pedal, providing a sound that is both immediate and degraded, offering a distinctive sonic character compared to other reverbs.
  • Intuitive and Interactive Controls: The control set is simple yet interactive, encouraging experimentation. The pedal offers quick and highly reflective reverb as well as slow and stretchy modulated reverb with noticeable pitched undulations.
  • Clock Slider: The Clock slider sets the timing of the entire system, affecting the sample rate that determines signal fidelity, the timing of the reverb, and the speed of the modulation within the reverb. It allows users to shift from fast and high-fidelity to slow and degraded effects.
  • Feedback Knob: Controls the intensity of the reverb and can lengthen the reverb decay, allowing for a range of reverberant sounds.
  • Mix and Volume Controls: Additional controls for Wet/Dry mix and Volume allow users to further shape the spatial characteristics of the reverb effect.
  • Soft-Touch Bypass Switching: The pedal features soft-touch bypass switching for ease of use.
  • Pedalboard Friendly Size: The BL-37 is designed in a compact size, making it suitable for pedalboard integration.
  • Made in the USA: The pedal is crafted with quality in mind and is made in the USA.
  • Power Requirements: Powered by a 9V DC PSU (center -, 2.1 mm, ~110 mA current draw).
