From the creative brains of Old Blood Noise Endeavors, the BL-44 Reverse is a pedal that contends with the existential construct of "time", as it actively seeks to push you to live your sonic life in reverse.

Through a highly intuitive and fun control set, this compact real-time reverse effect allows the user to instantly change the clock speed of the entire sonic system on the fly — letting you achieve sounds ranging anywhere from classic reverse, vivid harmonies to faded lo-fi memories.

Instant Recall, in Reverse!

BL-44 is a true reverse effect, meaning it will write what you've played to memory, then read that memory from end to start and play it back for you (but with added depth and harmony from the interaction of the Clock slider and Speed knob). It aims for an immediate and tactile experience that encourages the player to keep their thumb on the slider and experiment.

The magic, the extra twist, the "je-ne-sais-wow" if you like, all comes from the Clock slider. This slider determines the thinking speed of the digital signal processor and sets everything related to time. It influences the sample rate and the overall length of the reverse playback and as you slide it, you feel the pitch slide and resettle. Just like you'd expect, as you play with the forces of time!

Speed Control

In addition, you have a Speed control, which will cause the system to read through its memory in unexpected ways; catching bits multiple times or missing pieces as it tries to read at speeds different from what was written. Plus, you have volume and mix controls and an on/off switch.

Key Features

  • Reads backwards what was most recently played and adds depth/harmony.
  • Simple yet interactive control layout, for immediate tactile experience and to encourage experimenting.
  • Clock Slider: Changes the effect from fast and high-fidelity to slow and degraded.
  • Speed Knob: Affects the read speed of the reverse effect (adjust to create impression of octave-down, fifth-down, fourth-down, unison, fourth-up, fifth-up, or octave-up sounds).
  • Wet/dry mix control.
  • Soft-touch bypass switching.
  • Pedalboard-friendly size.
  • Made in the USA.
  • Powered by 9V DC PSU (centre negative, 2,1 mm, ~110 mA current draw).

Old Blood Noise Endeavors

Old Blood Noise Endeavors is a pedal manufacturer known for its creative and unconventional effects. Their pedals are designed to push the boundaries of traditional sound, often combining distortion, delay, and modulation effects in innovative ways. One example is their *Beam Splitter* pedal, which takes a single input signal and splits it into three different versions with varying delay times and overdrive tones. This results in a larger, more textured sound, ideal for those looking to create unique sonic landscapes. Their pedals also feature expressive controls such as Deviate, which introduces natural variations to delay times for a more organic feel.

Old Blood Noise Endeavors is also recognized for its distinctive pedal designs and collaboration with various artists, showcasing their commitment to producing high-quality, experimental tools for musicians. Their pedals are popular for both live performances and studio work, offering a range of effects from fuzz to reverb, each with a creative twist. This brand stands out for its bold approach to sound manipulation, making it a favourite among experimental musicians and those seeking to expand their sonic palette.

Octave

An octave pedal shifts your guitar signal up or down by one or more octaves, blending the altered pitch with your original sound to create a fuller, more complex tone. It can add a deep, bass-like layer underneath your playing or a shimmering high octave on top for lead lines and solos. Classic analogue octave pedals often produce slightly gritty, organic sounds, while modern digital versions track more precisely and can offer multiple octave ranges.

Octave pedals are great for thickening single-note riffs, creating synth-style textures, or even mimicking bass parts when playing alone. They pair well with fuzz or overdrive pedals for massive, harmonically rich tones. Whether you’re after vintage Hendrix-style octave fuzz or a modern polyphonic sound that tracks chords cleanly, an octave pedal opens up a world of creative possibilities and adds real weight and character to your tone.

Pitch

Pitch pedals alter the frequency of your guitar signal, changing the perceived note or adding harmony. They can shift notes up or down by fixed intervals, create harmonies, or produce dive-bomb and whammy-style effects without a tremolo arm. Pitch shifters and harmonisers are great for thickening solos, simulating multiple guitars, or experimenting with creative, otherworldly sounds that expand your tonal range.

Volume

Volume pedals control the output level of a guitar signal using a foot-operated treadle. They allow smooth volume swells, dynamic control during playing, and easy muting between songs. Volume pedals can be placed at different points in the signal chain to either control overall loudness or adjust gain and drive behaviour when positioned before distortion or overdrive pedals.
