The Old Blood Noise Endeavors Float Dual Filter is a filter pedal built around two independent filters in a single, pedalboard-friendly enclosure1. Guitar World described it at its 2022 unveiling as "technically" a filter pedal, but one that reaches well past the usual envelope-filter territory: the maker promises a range of classic filter sounds alongside stereo movements and modulations bordering on harmonic tremolo and phaser2. Delicious Audio's Paolo De Gregorio called it "a breath of fresh air in an effect niche that too often only caters to funk guitarists"1.
Two filters, one pedal
The core of the Float is two independent filters2. Each one carries its own full set of controls1:
| Control (per filter) | What it sets |
|---|---|
| Filter type | The character of that filter's response |
| Cutoff frequency | Where the filter sits in the spectrum |
| LFO rate | Speed of the filter's modulation |
| Envelope sensitivity | How strongly your playing dynamics drive the filter |
| LFO shape | The waveform of the modulation |
| Resonance | How pronounced the filter's peak is |
| Volume | Level of that filter's output |
Because each filter is controlled separately, the pedal can do straightforward single-filter duty or run both at once. Guitar World noted the two filters can be linked for reactive, moving effects that go beyond what a single wah or envelope filter offers2.
Stereo and routing
The Float is true stereo capable, with parallel mono and series mono operation, all via top-mounted jacks1. Using the two filters in tandem can create stereo movement, linked reactive elements, and modulations that approach harmonic tremolo and phaser sounds1. For players with a stereo rig or a stereo delay or reverb downstream, that makes the Float a routing-flexible filter rather than a mono one-trick box.
Expression control and bypass
An expression jack lets you externally control Cutoff or Rate for each filter1, so a connected expression pedal can sweep the filter frequency or its modulation speed by foot. Switching is soft touch with true relay bypass1.
The Float draws at least 100mA at 9VDC center negative1. Check that your supply's output can deliver that before adding it to a daisy chain.
Price and availability
Guitar World reported the Float available for $299 at the time of its July 2022 announcement2, and later coverage that August described it as recently unveiled3.

Questions
Is the Old Blood Noise Float analog or digital?
The Float is a digitally controlled analog pedal. Delicious Audio describes it as OBNE's first digitally-controlled-analog pedal, and Guitar World calls it the maker's premiere digitally controlled fully analog stompbox. In practice that means the filtering itself is analog circuitry, while digital control handles the switching and parameter management behind the knobs.
Does the Float Dual Filter work in stereo?
Yes. Delicious Audio lists true stereo, parallel mono, or series mono operation, all via top-mounted jacks. Running the two filters in tandem can create stereo movement, linked reactive elements, and modulations that approach harmonic tremolo and phaser, as well as classic filter sounds.
Is the Float true bypass?
Yes. The Float uses soft touch switching with true relay bypass, according to Delicious Audio's product page, so your signal passes through relays untouched when the pedal is off.
What power supply does the Float need?
The Float requires at least 100mA of 9VDC center negative power. That current draw is higher than many single pedals, so a low-output daisy-chain supply may not be enough; a dedicated isolated output rated at 100mA or more is the safe choice.
Can I control the Float with an expression pedal?
Yes. The Float has an expression jack to externally control Cutoff or Rate for each filter, so you can sweep the filter or its modulation speed by foot while playing.
How much does the Old Blood Noise Float cost?
Guitar World reported the Float available at a list price of $299 as of its July 2022 announcement.
