Leave Your Amp At Home.

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. Discover inspiring tube amp responsiveness, unprecedented impulse response speaker cabinet realism, and controllable natural sounding room ambience.

Go Direct With Gorgeous Tone.

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.

    Based on* a Fender® Deluxe Reverb

    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.

    Want to play live with the exact same tones that you use at home or in the studio? Or have access to multiple amp and cab setups without having to lug them on stage? Leave your amps at home, and connect Iridium directly to the house PA system.

    Going direct eliminates the need to mic an amp, giving sound engineers the option to send your amp and cab tone directly to a wedge or in-ear monitors. Instant adjustments to your tone are right there on your pedalboard, only a footswitch away. With Iridium, there are no menus to wade through—just familiar, responsive amp-style controls for instant, easy adjustment.

Direct Tone That Inspires.

With Iridium, it’s easy to dial in a direct guitar tone that will truly inspire and sound great whether you are monitoring through in-ears, floor wedges, reference monitors, or studio headphones. In this video, we take a look at the direct environments where Iridium shines.

  • Amp Research & Development

    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.
