I bought the EVH-5150 pack yesterday, to match with the 5150 III Blue model in the Axe-Fx II.
There are only 3 (three) IR's in the package, i also needed to convert them with CAB-LAB LITE, as there were only .wav files provided.
However, even it's only 3 IR's in the pack, they all sound very very good (but very similar)
and tbh much better than most IR libraries with 100000000 different speaker and mic combinations!
The Rosen IR's seem to be precisely engineered instead of being simply "guessed" when it comes to mic placement etc.
Well, OK, i need to write this a bit differently!
When you load them up for the first time, all you will hear is massive
apocalypse like bass, i mean extreme BASS, nothing like other IR's...
You have to turn back the DEPTH parameter down (which i always do anyway)
et voila, extremely good mix ready and clear/balanced sound!
Iam really stoked to try some other cabs, i was never really satisfied with IR's,
no matter which "brand" and version, even UltraRes didn't bring anyhthing "good" IMHO.
99% of the IR's i've tried (i did try A LOT) always sounded either boxy and flat, sterila or extremely boomy and muddy.
The Rosen IR's can sound bassy as hell but they are still clear, really hard to explain...it's better to try this on your own,
actually 8$ is a no brainer, so...
