Nothing reveals the true nature of your guitar and your playing like a world-class tube amp driving a perfectly matched speaker cabinet in a great sounding room. Now there is a pedal that truly delivers that sound and feel, with simple controls for effortlessly dialing in the perfect amp tone when going direct.
Iridium gives you three iconic amplifiers, with a total of nine impulse response speaker cabinets that complement the tonality of the amp.
Skip the hassle of lugging around or miking amps. Place Iridium on your pedalboard and send gorgeous stereo amplifier tones, stunningly realistic cabs, and lush room ambience direct to a recording interface or PA system.
With Iridium, it’s a snap to dial in a direct tone that will truly inspire and sound great whether you are monitoring through in-ears, floor wedges, reference monitors, or studio headphones.
Three Iconic Amplifiers
Our Matrix Modeling™ process captures all the subtleties and unique tonal qualities of each amplifier.
We’ve taken three iconic tube amps with distinct characters and mathematically modeled every aspect of their circuitry with absolute precision to deliver the response, feel, and inspiring experience of playing through the original amps at their best.
Taking the process a step further, we’ve hot-rodded each amp to provide an extended range of tonal options beyond what was available from the original designs.
Nine Stereo IR Cabinets
Iridium’s speaker cabinets offer a level of realism and responsiveness unprecedented in outboard effects.
Iridium delivers full stereo 24bit 96kHz resolution for the entire 500 milliseconds of its speaker cabinet impulse responses. Until now, IRs of this resolution have only been available for use within studio recording software.
Iridium’s breakthrough technology means you can use the very best impulse responses available, bringing maximum realism to your pedalboard.
Adjustable Room Ambience
Iridium’s hybrid room reverb combines a 256 millisecond stereo impulse response with Strymon’s reverb tank algorithm for extended decay.
This combination places your amp and cab in a natural sounding room (small, medium, or large), creating a space for your amp to open up and breathe.
The Deluxe is one of the most recorded amps in history for good reason. This amp is clean, bright, and mid-scooped, with plenty of headroom. At higher Drive settings it delivers an overdriven sound unique to its architecture.
We chose the Deluxe’s Normal channel for its round tone that plays well with pedals. While preserving access to all the tones originally available with this channel, our model gives you something extra: a midrange control. With the midrange at noon, you get the original fixed-resistor value and standard tonal characteristics of the Deluxe. Turn down the midrange for a more scooped sound, or turn it up for tweed-era tones.
Nine Stunningly Realistic Cabs.

Unprecedented IR Technology.
Image caption: More points equal far greater detail and realism than any other hardware IR device.
Impulse responses allow the sound and character of a mic’d speaker cabinet to be captured, so that any audio signal can be processed by the resulting impulse response and sound as if it’s being played through that exact speaker cabinet.
Iridium is able to deliver impulse response resolution far greater than any other piece of outboard gear.
With full 24bit 96kHz resolution for the entire 500 milliseconds of its speaker cabinet impulse responses, Iridium is able to use the absolute highest quality IRs available.
This means countless details are accurately preserved and reproduced to give you a completely real speaker response.
Every cabinet resonance, speaker vibration, as well as reflections between the cabinet, the mic, the floor, and the ceiling; all the minuscule cues that tell our brain we are listening to our favorite cabinet are preserved, providing completely lifelike realism.
Load Your Own Impulses.
It’s easy to replace the pre-installed IRs with custom IRs from your own collection by using Strymon Impulse Manager software.
Delivering the complete experience of playing into an amp through a miked cab in a room is a research and development project that has been years in the making.
The amp development began in the tube emulation and cascading gain stage topography created for Riverside, and then majorly leveled up for the intense degree of real-time calculation Matrix Modeling™ required to create Iridium’s amps.
We’re not just talking about the perfectly recreated tone stacks, but also things like the treble bleed on the gain controls, multi-stage power supply sag, and preamp and power amp tube emulation.
Our talented and tireless engineering team covered quite a bit of new ground on the way to recreating these classic amp designs with exact mathematical fidelity, and then expanded the capabilities of each amp in musically useful ways, giving you the full range of original amp sounds, and then some.
We knew it was theoretically possible to deliver our goal of 24bit 96kHz 500ms impulse responses, but we had to figure out how to do it in practice.
This part of the Iridium project turned out to be a five-year journey through adversity.
We started with a smaller proof-of-concept FFT (fast Fourier transform) based IR convolution with shorter-duration mono cab IRs, kept working on it, and eventually tore it all down and rebuilt so we could deliver the 24bit 96kHz 500ms IR cabs that we’d dreamed of for Iridium.
With these amazing amps and cabs, we wanted to create amazing spaces for them to live and breathe in.
When you are playing in a physical room, the first 80 milliseconds or so of early reflections are what really tell your brain what type of space you’re in.
The complexity of those myriad early reflections are very difficult to simulate with an algorithm.
That’s where impulse response technology is the perfect tool for the task.
After a certain duration, however, impulse responses become computationally expensive, and that’s where the algorithm shines: on the long tail.
The algorithmic portions of our room ambience were dialed in for each room, with delay lines tailored to enhance and meld with each specific space and room size. Creating a seamless transition between IR and algorithm was an intensive and artistic process that ultimately resulted in completely natural sounding rooms that feel great to play in and never distract.
Iridium makes the most of the powerful combination of a high-performance 32-bit floating-point SHARC ADSP-21375 processor working together with an ARM co-processor.
The SHARC is the perfect choice for handling the plethora of FFT instructions Iridium’s real-time sound processing requires, including adding and subtracting simultaneously.
We’ve created an optimized high-speed communications link between the two processors, and have maximized what the ARM co-processor can do.
Each turn of any of Iridium’s knobs sets off a chain of numerous coefficient calculations which we let the ARM co-processor handle, leaving the SHARC free to do its massive computational number crunching full-time at maximum capacity.
Besides stellar sound and responsiveness, this combination delivers super fast patch switching.
The ARM also provides USB connectivity and allows you to very quickly load and audition impulses with our Impulse Manager software.
Iridium is really a new class of device. You get IR resolution never before available in outboard gear, without paying a price in patch switching time, allowing you to select presets seamlessly with the speed you expect for live performance use.
Iridium, like all of our effects pedals, is built right here in Los Angeles, California.
There are many advantages to building our pedals within minutes of our design shop.
Most importantly, we control every aspect of manufacturing to ensure quality and consistency at every step of the process.
Every potentiometer, encoder, switch, LED, and audio component on every pedal is tested and re-tested.
Using the latest Audio Precision audio analyzing gear, each pedal must exceed our exacting audio quality standards.
