Strymon Iridium includes three matrix modeled guitar amplifiers and nine IR cabinet models. The 500 ms impulse responses, implemented at 24 bit / 96 kHz resolution, are unprecedentedly realistic. Iridium features a hybrid reverb, which includes traditional algorithmic reverb along with a 256 millisecond stereo reverb impulse for even more authentic room simulation. For home playing, the pedal also has a headphone output.
