hi kurt!
i DO like the iridium a lot.
i have not recorded a guitar track with a mic and cab since i got this thing.
well, that's not entirely true, but the one time i spent mic recording, i tossed the tracks afterwards,
to use newer Iridium tracks.
it doesn't have bass amp sims....
only the fender deluxe, the vox ac 30, and the marshall super lead 100 watt plexi.
but, a lot of prog rockers that i dig, that play bass, used marshall stacks to find their bass tones...
i'm using a closed back 4x10 bass cabinet impulse that i bought from Celestion.

now, some of my bass tracks are the marshall and 4x10 bass cab only...
but i also blend a lot of bass tracks by splitting the signal into 2 mono signals,
one to the iridium,
one to a Sansamp Bass DI, and i hpf and lpf to get the lowest lows clean from the sansamp,
and the body of the sound, drive and grit, from the Iridium.
works like a charm.
