The Old Blood Noise Black Fountain V3 is a delay pedal that captures the warm, modulated sound of vintage oil can delay units with a modern feature set, as the maker describes it1. It is a digital recreation of the oil can echo devices of the 1950s, a short-lived technology that players remember for its characterful, wobbly repeats2. The original Black Fountain was Old Blood Noise's first ever pedal, and the V3 is its third version, updated with tap tempo and subdivision switching2.
What is an oil can delay?
Oil can delays were echo devices built in the 1950s that used a rotating disc in oil to produce their repeats. Delicious Audio calls the technology "short-lived but full of character," and notes it was a favorite of Ry Cooder3. Guitar World describes the Black Fountain V3 as an "oil can-emulating delay pedal"5. Rather than hunting down a fragile sixty-year-old unit, the Black Fountain V3 models that sound digitally, then adds the conveniences of a modern pedal: tap tempo, subdivisions, an expression jack and true bypass12.
The controls and modes
The pedal has four knobs, Time, Feedback, Fluid and Mix, that shape the elements of whichever delay mode you select12. A central toggle switch chooses between three delay voices12.
| Control | What it does |
|---|---|
| Time | Sets delay time1 |
| Feedback | Sets repeats1 |
| Fluid | Sets modulation amount1 |
| Mix | Sets effect blend from 100% dry to 100% wet1 |
| Mode toggle | Selects Modern, Organ, or Vintage mode1 |
| Tap Tempo footswitch | Sets the tempo; hold down to momentarily max out feedback1 |
| Subdivision toggle | Selects quarter, eighth, or triplet subdivisions2 |
The three modes each give a different take on the oil can character2:
- Modern emulates the classic long delay of oil can units3.
- Organ and Vintage round out the three delay voices, selectable through the central toggle23.
Two taps of the Tap Tempo footswitch activate tap tempo, and the tempo can be subdivided into quarter, eighth or triplet values2. Holding the footswitch down momentarily maxes out the feedback, a quick way to get runaway repeats under your foot1. An expression jack lets you externally control Time, Feedback, or both, which opens up swells and pitch-bend-style delay tricks from an expression pedal1.
The bypass is a soft-touch footswitch for true bypass and minimal switch noise1.
What the V3 changed
The original Black Fountain was designed to capture the sound of vintage oil can delay units, and it was the company's first pedal2. Version 3 keeps that circuit goal but adds the timing features the earlier versions lacked. Gearnews summed up the update:
"Version V3 takes the popular effect and adds tap tempo to it."2
The additions are:
- Tap tempo, activated by two taps of the footswitch2
- Three subdivisions (quarter, eighth, triplet) through an extra toggle switch23
- A wider delay range, down to around 30ms or up to around 1 second2
Guitar World noted the Tap Tempo and Subdivision switches give more precise control over delay time and modulation rate5. Gearnews's reviewer called it "a sweet update to the company's first ever pedal" and expected the new features and tap tempo to make it even better overall2.
Price and availability
The Black Fountain V3 carried a list price of $219.004. When it launched in late 2020, Guitar World reported UK availability at £209 (approximately $275 at the time)5, and Delicious Audio reported it shipping that December3.
As of October 2026 the Black Fountain V3 + Tap Tempo shows as Sold Out on the maker's product page1. A limited colored version was offered for a short time through the blackbobbin.com site when the V3 launched2.
Players looking for other Old Blood Noise delay work can compare the Setback reverse delay, the Bathing liminal delay, or the Sunlight Stereo.

Questions
What is an oil can delay?
An oil can delay is a vintage echo device from the 1950s that used a rotating disc suspended in oil to create repeats. The technology was short-lived but had a distinctive warm, modulated character. The Black Fountain V3 is a digital recreation of that sound, with a modern feature set on top.
Does the Black Fountain V3 have tap tempo?
Yes. The V3 adds a Tap Tempo footswitch: two taps set the tempo, and the delay can be subdivided into quarter, eighth or triplet values. Holding the footswitch down momentarily maxes out the feedback for runaway repeats.
Is the Black Fountain V3 true bypass?
Yes. Old Blood Noise fits the pedal with a soft-touch bypass footswitch for true bypass and minimal switch noise when you kick it in and out.
What is the delay time range of the Black Fountain V3?
The delay time runs from around 30 milliseconds up to around 1 second, set with the Time knob or locked in with tap tempo. That range covers tight slapback through to long, ambient repeats.
Is there a limited colored version of the Black Fountain V3?
Yes. When the V3 launched, a limited colored version was available for a short time through the blackbobbin.com site. It was a short-run finish, so availability was limited from the start.
