Pigtronix Infinity 2

The Pigtronix Infinity 2 is a stereo double looper pedal from Pigtronix, announced in January 2020 as the second version of the company's Infinity looper. It carries two independent stereo loops, each holding up to five minutes, built around what Pigtronix describes as the high-fidelity audio and ultra-low-latency looping engine of the original Infinity Looper, in a smaller and simpler box¹²³.

The idea behind the pedal is what Pigtronix calls a verse/chorus workflow: you record one part on one loop, another on the second, and shuttle between them at the click of a footswitch, even mid-recording or while overdubbing¹⁴. It shipped to dealers worldwide at a MAP price of $199 USD⁵.

Two loops for verse and chorus

The core of the Infinity 2 is its pair of independent stereo loops, with one footswitch per loop: the switch nearest the volume knob handles loop one, the other handles loop two²⁶. Pigtronix says the pedal lets you switch between loops seamlessly, even during initial recording or while overdubbing, which is what makes the verse/chorus setup practical for live use¹. Sweetwater's Don Carr describes it as "two independent stereo loops for a verse/chorus workflow"⁶.

Beyond the basic double-looper setup, the pedal can run as a standard looper on the right footswitch while the left footswitch takes one of five selectable modes¹. It can also be configured for wet/dry routing, where output 1 is a dry pass-through and all loop material goes to output 2⁶. Guitar.com's news coverage also noted 24-bit/44kHz USB recording among its features³.

The controls

The panel is deliberately sparse: two footswitches, two knobs (Volume and Decay), and a soft-touch mode button²⁶. The mode button opens up the other functions of the Loop 2 footswitch when you are only using Loop 1, giving access to Undo, Stop, Once and Octave modes⁷.

The Decay knob is where the pedal gets deeper than its face suggests. Fully clockwise, loops play back continuously; fully counterclockwise, each overdub lasts only one cycle; in between, overdubbing creates constantly evolving loop textures that can be snapped back to a previous state with the Undo function⁶⁸. The assignable modes work like this¹⁷:

• Undo: removes the most recent overdub layer; tap again to bring it back.
• Stop: press once to stop at the loop boundary, twice to stop immediately, press and hold to fade.
• Once: press once for one more playback, repeatedly for a stutter effect, press and hold to play through.
• Octave: toggles the sample rate between 48kHz and 24kHz, slowing the loop by an octave.

The footswitch status lights tell you the pedal's state at a glance⁶:

• Off: no audio recorded
• Red: recording; green: playback; orange: overdubbing
• Blinking red, green or orange: that action will start at the loop boundary
• Slow blinking green: loop is stopped and audio is present

Power and connections

The Infinity 2 runs on 9VDC at 100mA draw¹. It has two separate inputs and two separate outputs that accept mono or stereo signals at instrument or line level, with stereo outputs and a high input impedance¹². There is also a TRS remote expression input¹.

An optional two-button footswitch from Pigtronix gives access to octave, once and stop modes⁶, and third-party makers such as American Loopers sell single-button aux switches for the stop function⁹.

From the original Infinity Looper

The Infinity 2 descends from the original Pigtronix Infinity Looper, which offered two stereo loops that could be configured to work together in several ways, with zero latency, and which received a 2.0 firmware update bringing significant upgrades¹⁰¹¹¹². The Infinity 2 simplified the existing user interface, smartened up the graphics and squeezed the ultra-low-latency looping engine into a compact stompbox³⁶.

The original Infinity Looper also offered a Loop 2 multiplier with settings of x1, x2, x3, x4 and x6, setting Loop 2's length as a multiple of Loop 1¹³. The Infinity 2 carries the same looping engine forward in a smaller box, and Pigtronix later moved the Infinity line on again with further versions in the series⁶¹.

What reviewers said

Reviewers found the Infinity 2 deceptively deep but still easy to use, praising its overall ease of use and depth⁶. Guitar Player listed it at $199 street¹⁴, and the reviewer found that as a standard looper plus assignable effects it becomes an ambient dream machine¹⁴¹.
