Should I not be experiencing this if I plug my guitar to the Axe-Fx III and use the output 3 to the amp?You can't use a DI box. It will load down your pickups dramatically as soon as you plug a cable into the XLR jack.

Correct. See my test clips.Should I not be experiencing this if I plug my guitar to the Axe-Fx III and use the output 3 to the amp?
Even my clip proved it. I'll add time codes to avoid confusion:And what I'm saying is that they do sound the same and there are clips to prove it.
Still no idea what you're saying. How do you put a "real amp through guitar"?
One clip is guitar->Axe-Fx->Ouput 3 to amp.
Another clip is straight into the amp.
The third clip is one or the other to keep you guessing.
I understood what you were trying to say but, that's not ideal in so many ways for what I'm trying to do. Thank you though.Let me rephrase:
a) Recording of the real amp (signal chain: Guitar->Real amp)
b) Recording of the real amp (signal chain: Guitar->Axe->Real amp)
c) Recording of the tone matched model (Signal chain: Guitar->Axe-Real amp)
I’m basically saying that putting both units in series shifts the resonat freq. and taking the real amp out on a fourth recording should produce a brighter sound like the one on case a)
But nevermind it
I hope to find a solution and wish and sincerely hope that I'm doing something wrong. This is not only about the Axe-Fx, like the test that I did with the DI box: guitar into passive DI with input through going to the amp in sounds completely normal, plug an XLR from the DI to anything and it changes the sound. If the sound difference was small I wouldn't care but it's really big right now. Here's a pic of the waveform difference:
Here's an audio clip:

And this happens on both my Mark V and Dual Rectifier.

Your clip sounds like it works perfectly. This is where I start to lose my sanity. I tried different cables, different outputs, different I/O settings, different everything. Eventually did a factory reset and I'm still experiencing this. Could there be a problem with other things connected to the Fractal?Correct. See my test clips.
There was no tone matching. Putting the units in series does not shift the resonant frequency because the output impedance of Output 3 is very low.Let me rephrase:

Could be something wrong with the input but I doubt it. Try using the rear input.Your clip sounds like it works perfectly. This is where I start to lose my sanity.

I'm using a borrowed loadbox for these clips, a Two Notes Captor, could that have something to do with this?Could be something wrong with the input but I doubt it. Try using the rear input.
The fact that the same thing happens with the Kemper points to cable issues though.
It's possible but I've never tried one. Load boxes can do all sorts of strange things due to the creation of feedback loops and such. I struggled with this with the LB-2. It took six iterations to get it right.I'm using a borrowed loadbox for these clips, a Two Notes Captor, could that have something to do with this?

I read about this on axewiki and tried all the different options out just in case.Another thing to check is to make sure your Input Impedance is set to 1M. If you have it set to Auto and there's an active block after the input it might be switching the input impedance.
Any word on the LB-1? Still waiting for it to be released or is it happening?I struggled with this with the LB-2. I took six iterations to get it right.
I'd be curious to know if the box is coloring the sound. Maybe record a quick few notes without loadbox (at 4:00AM so everyone will be too sleepy to complain about it.. )I'm using a borrowed loadbox for these clips, a Two Notes Captor, could that have something to do with this?
2 was direct into the amp. 1 and 3 were through the Axe-Fx then into the amp with 1 being the front input and 3 being the rear input. This is what would be expected given that the Axe-Fx input has slightly greater high frequency extension than a Recto.of Cliffs clips I liked 1 and 3 , 2 I did hear a slight muffling .
Doesn't surprise me. Like I said I struggled with this with the LB-2. There's so much power being dissipated that you end up with these funky ground loops that end up feeding current into the ground and right back to the guitar.@FractalAudio I found the problem: Two Notes Captor Reactive Loadbox. I tried these tests again and I was still having the problem. Plugged straight into my cab and used the Mesa slave out and I'm not having this problem anymore. Once again the lesson learned is:
THE PROBLEM IS NEVER WITH THE FRACTAL!
I actually found a way I can use the loadbox. Placing a DI inbetween the amp and loadbox is one way and also using the slave out on my Mesa amps. These work perfectly. It's the output of the loadbox that's messed up.
Yeah I did some tests with a miked cab vs Two Notes and an IR shot of that mic up. I essentially got a straight line but the low end had a scoop on it. Nothing too big though.. it was like 1dB or so but still, not flat.Doesn't surprise me. Like I said I struggled with this with the LB-2.

You should use a Suhr RL or an LB-2 though. Much more accurate impedance curves. The Two Notes (and the UA OX) don't use inductors for the low-frequency response so there's no low-frequency resonance. Instead the impedance curve has a "bathtub" shape. With the inductor you get a true low-frequency resonance but that inductor is big, heavy and expensive.
