The Old Blood Noise Float is a dual moving filter pedal from Old Blood Noise Endeavors, released in July 2022 for $2991. At its core are two independent filters, each with its own controls, that can be routed in true stereo, parallel mono, or series mono2. It is Old Blood's first digitally controlled analog pedal: the signal path is analog, while the control side is digital3. Development took two years4.
Guitar World described what it aims to do: "the Float vows to deliver, obviously, a range of classic filter sounds, but also a range of stereo movements and modulation" that the reviewer noted border on harmonic tremolo and phaser5. Old Blood's own description of the sounds runs from "quacky auto-wahs, shooting sonic laser beams or organically rising and falling filter landscapes" to "a mind-bending modulation device that can become everything from a phaser, a harmonic tremolo, a choppy or bubbly step-filter or an automated synth-like sweeper"4.
Two filters, one pedal
Each of the Float's two filters is a full filter voice on its own. Each can be set to low pass, band pass or high pass4, and each has its own volume, sensitivity, resonance, rate, wave shape and cutoff controls3. A toggle switch syncs the LFO or envelope elements of both filters, so they can move together or independently5.
The routing is where the pedal gets its range. With dual inputs and outputs, the two filters can run in series (one feeding the other), in parallel (both processing the same signal), or in true stereo (one filter per channel)3. Delicious Audio calls it "a dual filter pedal packed with creative features"7.
There are also hidden settings for LFO phase and envelope speed7, and a Sync On/Off mini switch that syncs the LFO or envelope of the filters6.
The controls on each filter
Each filter section carries the same control set, with two of everything on the face of the pedal3:
| Control | What it does |
|---|---|
| Volume | Sets the output level of that filter3 |
| Filter type | Selects low pass, band pass or high pass41 |
| Cutoff | Sets the filter's cutoff frequency; implemented as a slider for easy live tweaking6 |
| Resonance | Sets the emphasis at the cutoff point3 |
| Rate | Sets the LFO speed3 |
| Sensitivity | Sets envelope sensitivity, how hard you play to trigger the sweep3 |
| Wave shape | Selects among 6 LFO shapes6 |
The cutoff control stands out ergonomically: Gearnews noted it "has a nice easy to manipulate slider for each filter section, making it easy to tweak live during a performance"6. Each filter also has its own low/band/high-pass filter and bypass footswitch, two of each on the pedal3.
An expression jack lets an external pedal control Cutoff or Rate for each filter7, so you can sweep the filter frequency or the LFO speed by foot.
What it sounds like
Published impressions of the Float in play point in two directions. Guitar.com's news coverage said that "in play, Float offers shrill high neck sounds and layers of extra sludgy-ness over your distortion"8. Guitar.com's full review found the stereo configuration the most rewarding: "perhaps the Float's best feature is its musical duality when running a stereo setup," a lush pulsating effect the reviewer called unique to this pedal3.
Guitar World's reviewer noted that the Float resists being placed in a single category, describing it as technically a filter pedal while it also delivers the kind of sustain and harmonic color players usually reach for elsewhere5.
Power and setup
The Float runs on 9V DC, center negative, drawing 100mA2. Delicious Audio specifies that it requires at least 100mA of 9V DC center negative power7, so it is not a pedal to share a low-current output or a basic daisy chain.
The Float needs at least 100mA at 9V DC, center negative7. Check your power supply's per-output rating before plugging it in alongside high-draw digital pedals.
Where it came from
Old Blood Noise Endeavors announced the Float in late July 2022 as its first digitally controlled analog pedal3. MusicRadar reported that the Dual Moving Filter was "the result of two years work"4. It launched at $299 and was available from release5.

Questions
What filter modes does the Old Blood Noise Float have?
Each of the Float's two filters can be switched between low pass, band pass and high pass modes, selectable independently per filter. The two filters can also be synced together, so their LFO or envelope elements move as one, and routed in stereo, parallel mono or series mono configurations.
Can the Old Blood Noise Float run in stereo?
Yes. The Float has dual inputs and outputs and runs in true stereo, parallel mono, or series mono. Guitar.com's reviewer found its musical duality in a stereo setup to be perhaps the pedal's best feature, describing a lush pulsating effect unique to it.
How much current does the Old Blood Noise Float draw?
The Float draws 100mA and runs on 9V DC with a center negative plug. Delicious Audio notes it requires at least 100mA, so it is not a pedal to run from a low-current output on a small power supply.
Does the Old Blood Noise Float have an expression pedal input?
Yes. An expression jack lets an external expression pedal control either the Cutoff or the Rate of each filter, so you can sweep the filter frequency or the LFO speed by foot in real time.
How many waveshapes does the Float have?
Each filter offers six LFO waveshapes on its wave shape control. With two filters, that gives you a wide range of movement textures, from smooth sweeps to choppy stepped patterns, and the two can be synced or left independent.
