The Old Blood Noise Endeavours Bathing is what its maker calls a "liminal delay": a delay pedal that sits in the borderland between delay, phaser and reverb. Old Blood Noise describes it as "perhaps a reverb, or a phaser, or a classic delay, but never exactly any one of these things. It's a style of effect unique to the Old Blood lineup"1. Guitar.com's reviewer put it more technically: "Technically, it's between a delay, a phaser and a reverb"2.
The circuit is digital: a digital delay modulated in several complex ways by a resonant LFO in the feedback loop, with extra pitch modulation2. The dry signal is kept analog via analog dry-through3. The design expands on the "phase repetition" idea from Old Blood Noise's Dweller pedal, turned into a stereo unit with presets and MIDI34.
A delay that sits between phaser and reverb
The Bathing's behavior depends heavily on where the Time knob sits. With Time very short, the LFO acts like a modulation effect, producing phaser or flanger sounds. With Time set longer, the repeats scatter anywhere from a single repeat at the central delay time out to many diffused repeats around that time4. Fewer stages create tight, flanged tones, while longer times and more stages generate cascading repeats both before and after the central delay4.
Guitar.com's reviewer, Cillian Breathnach, described what happens at longer delay times: "When you set the delay time longer, the LFO starts to pull your repeated signal apart, leading to cascading, marble-down" sounds, with repeats phasing outwards and orbiting the main delay time2. Gearnews noted the range of characters available: "it can sound like a granular, like a phase-y room reverb, and even like the most spaced-out, analog delay"6. Delicious Audio groups its modes as delay, phaser/flanger, and multi-tap reverb with diffused, scattered echoes5.
The pedal is the third installment of Old Blood Noise's Square series6, and Guitar Pedal X describes it as taking the "phase repetition" of the Dweller and massively expanding it into a stereo unit combining delay, modulation and reverb in one box3.
The controls
The maker's product page lists the control set1:
| Control | What it does |
|---|---|
| Time | Sets the central delay time; hold the Tap footswitch to choose between six subdivisions |
| Wet | Sets the volume of the delay |
| Filter | Darkens or brightens the character of the delay |
| Feedback | Sets the overall feedback amount |
| Dimension | Adds subtle stereo chorus (or mono vibrato) to the wet signal |
| Stages | Adjusts how many extra repeats there are2 |
| Depth | Adjusts how far out the phase-scattered repeats go2 |
| LFO rate | Runs from stopped dead at position zero up to audio-frequency, ring-mod levels on max2 |
| LFO wave selector | Chooses from discrete wave shapes including sine, sawtooths and envelope-activated ramps2 |
The Filter knob is wide ranging: depending on its position, repeats can wash out into underwater bassiness or sharpen into walkie-talkie crackle, with neutral in the middle2. The LFO wave shapes are described as very impactful, ranging from a standard sine to disorienting sawtooths2.
Two footswitches handle bypass and tap tempo, with enough room between them to be hit individually2. The Tap/Aux switch taps in tempo, holds for infinite feedback, or can optionally serve as a preset switcher1. Expression control is available over every knob1.
Not every control is a full-size knob. Guitar.com's reviewer found the dry/wet mix and chorus depth controls are PCB-mount mini pots that are fiddly and less of a joy to turn, and the LFO wave selector frustrating because it rotates continuously despite selecting discrete settings; he suggested a selector switch would be better2.
Stereo, MIDI and connections
The Bathing is a stereo pedal that can work fully mono, fully stereo, or in MISO (mono in, stereo out)2. In Mono-in, Stereo-out and full stereo modes, the LFO is offset across the left and right channels to create a variety of stereo effects4. Stereo connections are accessed via TRS jacks2.
The rear panel carries In (TS/TRS), Out (TS/TRS), MIDI In, MIDI Out, USB-C, Expression, and 9V DC power at 350mA3. MIDI control covers everything in the pedal, including MIDI clock in and out for external syncing1, and presets can be saved and recalled via footswitch or MIDI5. Guitar.com's reviewer appreciated that all of the I/O, expression jack and MIDI included, sits in one place2.
The pedal uses Old Blood's newest enclosure format: a slightly sloped bent-steel enclosure with an overhang on the front side2. It ships in three colorways, Algae (the standard finish), Orchid, and Ink134.
What reviewers said
Guitar.com's review rated the Bathing 8 out of 10. The reviewer's verdict praised the gorgeous sounds and art, the totally unique signal path, and the extensive I/O and MIDI support, while noting that sounds can get quite extreme quite quickly and that a couple of the controls are fiddly2. He found the pedal "indeed pretty unique and intriguing," with hours of noodling lost in use, and said it "makes good on the promise of being 'liminal'" with profoundly strange and evocative sounds from a totally weird signal chain2. The artwork he called "a gorgeous illustration that to me evokes the clean lines and abandoned fantasy visuals of something like Hyper Light Drifter"2.
Gearnews wrote that the Bathing "offers sounds and effect possibilities you get nowhere else"6. Guitar Pedal X found the overview details a little skinny without the manual but still called it a very compelling effect, highlighting its wide control set, low noise floor and expansive stereo field3.
Compared with the Chase Bliss Habit
Guitar.com's reviewer grouped the Bathing with the Chase Bliss Habit as effects that resist easy categorization2. Where the Bathing's LFO can be stopped dead at position zero or pushed to audio-frequency, ring-mod levels on max2, the Habit takes a different approach to delay, and the reviewer treated the two as pedals that sit outside the usual categories rather than as direct rivals2.

Questions
Is the Bathing analog or digital?
It is digital. Its signal path is a digital delay modulated in several complex ways by a resonant LFO in the feedback loop, with extra pitch modulation. The dry signal passes through analog dry-through, so your untouched guitar signal stays analog from input to output.
Does the Old Blood Noise Bathing have MIDI?
Yes. The maker lists MIDI control over everything in the pedal, including MIDI clock in and out for external syncing. There are MIDI In and MIDI Out ports on the rear panel, and presets can be saved and recalled via footswitch or MIDI.
Can the Bathing run mono in, stereo out?
Yes. It works fully mono, fully stereo, or in MISO (mono in, stereo out). In Mono-in, Stereo-out and full stereo modes the LFO is offset across the left and right channels to create a variety of stereo effects. Stereo connections are accessed via TRS jacks.
What colors does the Bathing come in?
It ships in three colorways: Algae (the standard finish), Orchid, and Ink. The pedal uses Old Blood's newest enclosure format, a slightly sloped bent-steel enclosure with an overhang on the front side.
Does the Bathing have tap tempo?
Yes. The Tap footswitch taps in tempo, and holding it chooses between six subdivisions. The same Tap/Aux switch can also be held for infinite feedback, or optionally configured as a preset switcher.
How does the Bathing compare to the Chase Bliss Habit?
Guitar.com's reviewer grouped the Bathing with the Chase Bliss Habit, a sort-of-delay sort-of-looper priced at $339, as pedals that sit between categories. The Habit collects and dissolves echoes, while the Bathing scatters repeats around a central delay time with phase and reverb-like textures.
