What is Iridium?

Iridium is an amp modeler that provides you with 3 classic tube amplifier circuits which can be paired with one of 9 ultra- realistic, full stereo Impulse Response (IR) speaker cabinets.


  • round – Based on a Fender® Deluxe Reverb®*
  • chime – Based on the Brilliant channel of a Vox® AC30TB*
  • punch – Based on a Marshall® Plexi*

Every aspect of the amplifier’s circuitry has been mathematically modeled 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.

Impulse Response Speaker Cabinets

Iridium delivers full stereo 24bit 96kHz resolution for the entire 500 milliseconds of its speaker cabinet impulse responses, allowing you to use the very best impulse responses available.  We have provided a curated set of 9 speaker cabinet IRs from top IR vendors, Celestion®, Ownhammer®, and

Additionally, you can load your own IR files to Iridium’s 9 cab slots using our free Strymon Impulse Manager software.

Room Ambience

Iridium features a hybrid room ambience design that combines 256ms impulse response captures of real rooms for realistic early reflections, with an algorithm for extended decay and modulation. This combination places your amp and cab in a natural sounding room, creating a space for your amp to open up and breathe. In addition to controlling the amount of room ambience, you can also choose a small, medium, or large room.
