I will chime in here.
I received one of these last week. First off, the packing was top-notch, I had worries that UPS would throw it around during the holiday season....wouldn't have mattered....even the cardboard Matrix uses on their shipping boxes is high quality.
Secondly, it is very light and I had my doubts.....is this thing a toy or a real piece of audio equipment???
Plugged it in. Out 2 > GT800 > NL212 (no cab sim) Out 1 > CLR. Time to compare. FWIW, I received my CLR around the 1st week they were out and have been gigging it ever since. I really like the CLR. BUT.....I missed that "cab in the room feel"...not trying to start a debate.
I have many cab IR packs, Producer pack, OH, Redwirez. I generally use the Basketweave 4x12(Axe producer pack) with 2 separate mics in a stereo cab block. I have found that if I pick an IR I like then I can spend less time tweaking when new FW updates come along. I get tired of "IR tone chasing" especially if my main use with the Axe is playing live and not recording.
Well....I first turned up Out 1 and played some nice Cult licks and said.....ahhh...this CLR sounds so good. I like getting new stuff and being patient before trying it so I continued to play for about 30 minutes all the while the Matrix was fired up and just begging me to turn up the Out 2 knob.
So, while the CLR was still fresh in my head I turned down Out 1 and slowly raised Out 2.......hmmmmmm. Cab in the room tone to die for. I couldnt believe how chewy and thick it sounded. I really like it, full and very balanced. The highs are not shrill and the bottem end thumps nicely. I keep the far left Global EQ sliders bottomed out on my Axe.
So after enjoying this a while (using a BE, HBE and Plexi Jumpered) I went back to the CLR. The CLR still sounded great but "different" I think I prefer the Matrix NL212 better for jamming or playing with a band(although we havent had practice since I received it). I still need some more time with it.
The one thing I found very interesting was that when playing both side by side...I found that the cab sim/IR I had been using sounded very similar so if I choose to use the NL212 live and run Out 1 to FOH I think I will be ok without much tweaking. I did find that a PEQ for Out 1 with the IR helped get closer to the NL212's meaty thick sound.
Hope this helps some of you who were on the fence as I was. This is just my personal take.
I am completely happy with the NL212, quality is top-notch and the company has been great answering my emails prior to my purchase.
Thanks Matrix!
