The Pigtronix Infinity 3 is a stereo double looper pedal released in June 2021 at $419, the latest version of Pigtronix's flagship stereo looper line123. It gives you two stereo loop pairs that can be played back in series or in parallel, synchronized or run independently, with instantaneous record, playback, dub, undo and redo45. Around 3 hours of recording time is available across up to 50 loop pairs, captured by a 24-bit HD recording engine46.
Pigtronix markets it as "the most musical looper" on the market, a claim Guitar Player repeats alongside its robust, all-black metal chassis, high-quality metallic footswitches and heavy-duty rotary knobs7. It was announced alongside a companion three-footswitch Universal Remote controller, and both were available at launch12.
Two loops, series or parallel
The core idea of the Infinity 3 is that it holds two separate tracks rather than one. You can play them back both at once, run them in series or in parallel, and sync the two channels or leave them independent67. Strymon's looper buying guide adds that the second loop can be a multiple of the first loop's length, so a short verse loop can sit under a longer structure10. Guitar Player's take: "Having two separate tracks for looping makes it an excellent songwriting tool"7.
Each loop pair can be cued'd for automatic playback, and the pedal handles record, playback, dub, undo and redo instantaneously4. Pedal of the Day reports the Infinity 3 "guarantees latency-free looping"4.
The audio path combines analog and digital elements: discrete analog limiter stages, transparent analog pass-through, and the 24-bit HD recording engine with a variable sample rate that can be incremented in semitones over two octaves5. That variable sample rate is effectively a pitch control over your recorded loops.
The controls
The black enclosure carries three footswitches: a Stop switch for halting loop playback or erasing your loop, plus dedicated footswitches for Loop 1 and Loop 22. On top, rotary knobs control the volumes of the two individual tracks, and a further knob scrolls through preset configurations; you can save your own presets too6.
| Control | What it does |
|---|---|
| Loop 1 footswitch | Records and controls the first stereo loop pair2 |
| Loop 2 footswitch | Records and controls the second stereo loop pair2 |
| Stop footswitch | Stops loop playback or erases your loop2 |
| Track volume knobs | Rotary knobs setting the volume of each of the two tracks6 |
| Preset knob | Scrolls through preset configurations; user presets can be saved6 |
Pedal of the Day found the interface quick to internalize: "once you sit down and start playing with it, controlling [Infinity 3] becomes like second nature," and noted it can be used as a stripped-down, easy-to-manage looper if you do not want the deeper features4.
Power and connections
The Infinity 3 requires an 18V power supply, which it comes with. Guitar World's reviewer warns that a usual Boss 9V plug will not work, so plan a dedicated output on your power supply rather than a shared 9V daisy chain6.
Full specifications as listed by Guitar World6:
| Specification | Value |
|---|---|
| Power | 18V DC, 200mA (supply included)69 |
| Bypass | Buffered6 |
| Record time | 3 hours6 |
| Audio quality | Up to 48kHz/24-bit6 |
| Input impedance | 1M6 |
| Output impedance | 150 ohms6 |
| Expression | TRS 10K or 0-5V CV, TRS Remote, MIDI6 |
| Dimensions (L x W x H) | 5" x 7.4" x 2.4"6 |
| Weight | 1.2 lbs6 |
Beyond the main stereo outputs, the Infinity 3 can run loop audio out two separate outputs in addition to the main output, so you can send your loop to a different destination than your live signal10. It also has stereo split inputs4.
MIDI and syncing
The Infinity 3 has comprehensive MIDI control with intelligent MIDI clock jitter correction, giving it the ability to link to a DAW, a drum machine or other effects pedals14. MusicRadar's looper buying guide calls it "a breeze to set up with MIDI-enabled pedals, groove boxes and synthesizers"9. Strymon's guide highlights the same strength for players building larger rigs9.
Infinity 2 versus Infinity 3
The Infinity 3 supersedes the Infinity 2 model from 202011. The Infinity 2 was itself a stereo looper with a pair of independent loops, dual stereo loops and stereo inputs and outputs, running on 9V DC at 100mA with a 1k output impedance1213. The Infinity 3 steps up to 18V at 200mA, adds MIDI control with clock jitter correction, expands to up to 50 loop pairs and roughly 3 hours of recording, and brings in the 24-bit HD recording engine with its variable sample rate456.
What reviewers said
Guitar World's Chris Corfield reviewed the Infinity 3 and summarized it as "intuitive, looks great and is simple to use, yet has enough complexity to appeal to experienced players," calling it easy to recommend overall6. MusicRadar's buying guide picked it as its choice for live looping, finding that "with it simple operation and depth of features, the Infinity 3 is perfect for players who want to live loop"9. Guitar Player's guide praised the build: "Built with a robust, all-black metal chassis and featuring high-quality metallic footswitches and heavy-duty rotary knobs"7.
"Jam-packed with features, Infinity 3 allows for every looping possibility, including MIDI-sync options, stereo split inputs, extra features via the Pigtronix Universal Remote and much, much more."

Questions
Can the Pigtronix Infinity 3 run on a 9V supply?
No. The Infinity 3 runs on an 18V DC supply drawing 200mA, which is included in the box. Guitar World's reviewer notes that a standard Boss-style 9V plug will not work, so it cannot share a typical 9V daisy chain with the rest of a pedalboard.
How long can the Infinity 3 record?
Up to about 3 hours of recording time, spread across up to 50 loop pairs. Audio quality is up to 48kHz/24-bit, and the recording engine has a variable sample rate that can be incremented in semitones over two octaves.
Can the Infinity 3 sync to a drum machine over MIDI?
Yes. It has comprehensive MIDI control with intelligent MIDI clock jitter correction, so it can link to a DAW, a drum machine or other MIDI-enabled effects pedals. MusicRadar's buying guide calls it easy to set up with groove boxes and synthesizers.
What is the difference between the Infinity 2 and Infinity 3?
The Infinity 3, released in June 2021, supersedes the Infinity 2 from 2020. It adds MIDI control with clock jitter correction, up to 50 loop pairs and around 3 hours of recording, and a 24-bit HD recording engine with a variable sample rate. The Infinity 2 runs on 9V; the Infinity 3 needs 18V.
Is the Infinity 3 true bypass?
No. Guitar World lists its bypass as buffered. Pigtronix describes the pedal as having transparent analog pass-through with discrete analog limiter stages, so the dry path goes through analog circuitry rather than a true bypass switch.
