The second amp, Chime, is a Vox AC30
Top Boost with a mid control that works
just like the original’s Tone Cut for top end
roll-off. The full gain range of the original
amp is reproduced but the upper reaches
of the gain knob adds a bit extra with the
cab choice (including a Mesa 4x12) adding
more versatility.
Punch is based on a 100-watt Marshall
Super Lead the classic ‘Plexi’ model.
While a Plexi at full whack sounds
glorious, it only goes so far, so Strymon has
added extra whomp after two o’clock on
the Gain knob, getting towards high gain.
If you need more, the Iridium takes drive
pedals really well.
While all of the amps/cabs sound classily
authentic anyway, you can open the whole
sound up to whatever degree you need
with the sense of realistic space provided
by the room reverb.
VERDICT
This pedal is all about the provision of
the three most classic amp flavours with
a minimum of fuss. Unlike the Kemper,
Helix and Fractal’s Axe-Fx where you can
navigate the menus for a massive choice of
models, the Iridium is sharply focused: it
has exactly whats necessary and no more.
There’s a simplicity and ease of use that
has massive appeal. You could simply
use it as a tabletop recording tool to
instantly give you the sound of a great
amp recorded at a decent working volume
with professional mics in a nice-sounding
room (without the need for amp, mic
or room). Alternatively, you could take
advantage of its form factor and integrate
it into your pedalboard, turning that ’board
into a full rig for headphone practice, for
gigging direct into the sound system if you
prefer not to use an amp or can’t travel
with one, or maybe as a belt-and-braces
backup ready for use if your amp goes
down. Strymon has identified a need that
guitarists didn’t know they had and has
filled it brilliantly.
