Is there any guides on usage of advanced parameters like negative feedback, presence frequency & depth frequency? Or should it be considered more trial and error?
I’m trying to do a real amp vs Axe FX III comparison. My goal was to post a video online. But I’m struggling to get the Axe to sound identical to the real tube amp.
I have a side by side setup in my room.
1) Mesa TC100 into Mesa 2x12 Vertical Rectifier Cab.
2) Axe FX III into Matrix GT1000FX into identical Mesa 2x12 Vertical Rectifier Cab
Proof provided with the attached photo.
I’ve matched all amp settings.
I’ve tweaked Low Freq settings in the Speaker section.
Yes, cables are fine.
Yes, power amp modelling is on.
Yes, I’m aware cabs are not always identical but I’ve flipped cables and the difference follows the cable.
There’s a really low frequency thump in the real amp that I was struggling to reproduce with the AF3/Matrix amp. Mostly noticeable with palm mutes on low notes on the A string. With the AF3 there’s a dull thud. With the TC100 there’s a huge boom in the low frequencies. But the higher notes are crystal clear, there’s no mud from the low end.
I’ve fiddled around with input and output eq as well but haven’t had much success. The closest I’ve been able to get is to start deep diving and adjusting the negative feedback, presence frequency & depth frequency. That starts to bring in the low frequencies that were missing. But it’s still not perfect.
So my questions are, is there any guides on utilization of these parameters and going into a guitar cab (beyond what’s mentioned in the manual). Also, is what I’m trying to accomplish simply not possible? Will there always be a difference? Don’t get me wrong, the AF3 setup sounds absolutely amazing but I want to make the two setups indistinguishable. Just to say I can do it more than anything and also provide a demo for others. The more I learn here I’m happy to share with others and even work on a guide. @FractalAudio has said that he’s done an A/B before and can’t tell the difference. @FractalAudio did you have to deep dive into the negative feedback/depth settings to accomplish this? Perhaps it’s just this particular amp model?
Looking forward to any input as I’ve been tweaking for a few weeks now. This isn’t critical, more of an exploratory situation. I’m really enjoying what I’m learning along the way!
