Old Blood Noise Endeavors BL-82

The Old Blood Noise Endeavors BL-82 is a chorus pedal from the Oklahoma boutique maker, launched in April 2023 as what Guitar World called a "Variable Clock Effector"¹. Where a conventional chorus gives you fixed rate and depth knobs, the BL-82 puts almost everything on a single diagonal slider called Clock, which sweeps the pedal from a shimmering chorus at one end to a long, deeply modulated delay at the other. Old Blood Noise describes it as a chorus that "challenges the definition of chorus, managing to be both lush and grimy"².

The maker's page currently lists the BL-82 as Sold Out in its Retirement Black colorway, so it is not available new at the time of writing².

What the BL-82 does: chorus that turns into delay

Under the hood, the BL-82 runs two delay lines modulated by opposite synchronized LFOs (low-frequency oscillators) combined in parallel, which is what produces the swirling, three-dimensional modulation⁶. Delicious Audio calls the pedal "an ode to delay time," because the Clock slider varies the slight delay at the heart of the modulated sound, and that one change reshapes everything at once: the effect's depth and speed, and the quality of the delay itself, which degrades at longer settings³.

At the top of the slider's range you get what the maker describes as "a shimmering three-dimensional mono chorus"; at the bottom, "a long, deeply modulated delay, with many textures in between"². Guitar.com noted that because of how the circuit behaves, the BL-82 sits somewhere between chorus and flanger rather than being a straight take on either⁶. Old Blood Noise itself said the pedal seeks to unapologetically:

The controls: Clock slider, Feedback, Mix and Volume

The BL-82 has four controls: three knobs and the central Clock slider. Gearnews called the slider "the main standout control"⁵.

The Clock slider is the one doing the heavy lifting. According to Guitar World, the speed and depth of the LFOs, as well as the delay line time, are all adjusted by that central slider¹. Delicious Audio points out that a control named Clock is rarely found on choruses, and that it affects at once the effect's depth and speed but also the quality of the delay, which "tends to degrade at longer settings"³. That degradation is part of the design rather than a fault: it is how the pedal earns the "grimy" half of the maker's own description².

A single soft-touch footswitch engages or bypasses the effect, with true bypass so the dry signal is untouched when the pedal is off².

Power: 9V DC, 110mA

The BL-82 requires a 9V DC center negative power supply with a 2.1mm jack, capable of supplying 110mA, and the supply is not included². There is no battery option, so it needs a spot on a powered pedalboard or a dedicated adapter. At 110mA it draws more than a simple analog boost but well within what a typical isolated supply's 100mA-plus outputs can handle.

The BL line and the Retirement Black edition

The BL-82 belongs to Old Blood Noise's BL line, a series of compact pedals built around the same slider-driven layout²⁷. Guitar World noted that the BL-82 Chorus follows the company's "similarly mind-bending" BL-44 Reverse, and Gearnews reported that it is related to the earlier BL-4 Clock Reverse Effector in terms of layout¹⁵. The BL-44 Reverse carried the same four-control format of Mix, Volume, Speed and a Clock Slider, and like the BL-82 it was offered in a Retirement Black colorway alongside a standard finish⁸⁹.

The enclosure art on both the BL-44 and the BL-82 is an original painting by Brandy M. Patterson of Manchester, New Hampshire²³. Guitar.com described the BL-82's enclosure as a "pedalboard friendly size"⁶.

The BL-82's own status is Sold Out on the maker's page². Its sibling fared the same: Delicious Audio reported in 2026 that "OBNE killed the BL-44," so the BL line's slider-era pedals have been retiring one by one¹⁰.

What reviewers said

Coverage at launch was largely descriptive, since the pedal's premise invited explanation. Gearnews' reviewer found the demos gave "a good indication of what to expect from this unconventional chorus effect," while separately wishing for top-mounted jacks⁵. Guitar.com highlighted the variable clock control that shifts "between shimmering chorus and chaotic modulated delays," and noted the pedal's position between chorus and flanger territory⁶. Delicious Audio framed it as a boutique American take on the modulation circuit, with the Clock slider as its distinguishing feature³.

On price, the maker's page lists $179.00². At launch, UK coverage put it at £189 GP⁶, and Gearnews later listed it at $199.00 / £183.00 / 209.00€ at Thomann in July 2023¹¹, with a 2025 buying guide still citing 209 euros at Thomann¹². The figures differ because they come from different dates and retailers; the maker's own current figure is the $179.00 list price.
