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.
