In this thread this morning http://forum.fractalaudio.com/axe-f...krod-model-how-dare-i-doubt-2.html#post712632, InsideOut and I had started a conversation about the TMA blocks in Cliffs presets and whether the information in the TMA contained the speaker cab IR information as part of it. I had asserted that if an IR of the speaker cab being used in the amp match was used during the TMA matching process (was part of the signal chain), that what was contained in the TMA after the match process was essentially only the amp information. Damn. Now I know I have to read that again, hopefully it makes sense.
The bottom line however is this, if you take my Splawn Quickrod presets or any of Cliffs TMA presets and bypass the cab, you can use a FRFR PA and any guitar cab of you choice.
So to back up my assertion, I did an experiment during my amp match session from http://forum.fractalaudio.com/axe-f...-adventures-tone-matching-stuff-part-2-a.html.
After I had completed the amp match process, in which I used an IR of the actual physical guitar cabinet, I recorded the AxeFx II playing through a FRFR PA and my favorite Avatar Celestion loaded 2X12 guitar cab (the same one I used during the amp match) with the cab sims globally bypassed. I then recorded the AxeFx II direct with the cab sims globally activated. Here are the results
Here is what the two look like compared within a frequency spectrum analyzer.
The light blue is the physical cab take, the purple is the IR take. Almost exactly the same. I believe the very small differences are in playing between the takes.
It conclusion it appears to my ears and eyes that there is no perceivable difference in the two samples.
Please chime in and let me know your thoughts!
