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.

Strymon Iridium amp & IR cab

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 Amps We've Always Wanted.

Round Amp

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.

Chime Amp

Based on* the Brilliant channel of a Vox® AC30TB

The amp that defined the guitar sound of the British Invasion. Our model of the AC30TB Brilliant channel is jangly, bright, and chimey, providing air for subtle passages with a light touch, and bite when you want to dig in. For this amp, the Middle knob acts a Tone Cut knob, providing high-end roll-off just before the power tubes, per the original AC30 design. In addition to the full available gain of the original amp, toward the top end of the Drive knob’s range of travel, we’ve added a frequency-shaped front end boost to tighten the low end while driving the amp further into saturation.

Punch Amp

Based on* a Marshall® Plexi (Super Lead model number 1959)

This powerful amp is meatier, with higher gain than the other two amps, and has a powerful midrange response. This amp features a buttery, smooth overdrive. At higher Drive settings it will deliver all the high gain distortion and growl this amp is known for, and then some. Setting the Drive control at around 2 o’clock gets you the maximum gain the original Plexi design allowed. Beyond that, our model has some additional gain on tap, giving you access to custom hot-rodded Plexi high gain tones.
