Display More@AndyT89 i’ve just watched the video. He is simply running basic 4CM as you would with a traditional amp/pedal board but with an extra preamp from the Headrush as an overdrive/distortion pedal effect.
Most of what he describes can be done in the Kemper but it isn’t what you described in your question. The guy’s description in the video is a little confused in places and some of what he says isn’t quite right. For example he talks about “replacing” the pre amp of the Quilter with the Headrush pre amp. This isn’t happening. What is really happening is he is running the two preamps sequentially and changing the order. They are both still on.
However, the main thing about the set up that differs from you original question is that he is basically using the Quilter amp as a clean pedal platform rather than as a significant part of the overal tone. You would get similar results running the Headrush or Kemper into a clean power amp and speaker as he is not relying on the drive characteristics of the Quilter. He is NOT capturing the final signal path from the Headrush AND amp to send to FOH. In order to capture the full path to send to FOH you would need to stick a mic in front of the cab.
The signal going to FOH is Gtr>HR FX and pre amp>Quilter PreAmp>HR FX post>HR CabSim.
The signal In the room is Gtr>HR FX and pre amp>Quilter PreAmp>HR FX post>Quilter Power Amp>Quilter Cab. To get that to FOH you need a mic or a loadbox with IRs like a Two Notes Torpedo.
Depending on how you use the real amp those two signal paths might be quite similar or could be worlds apart.
The way to achieve The true glory of your Archon is simply to profile the Archon with your settings and speaker. Then use that in the Kemper chain along with the Kemper FX. Send one signal to FOH and the other to your onstage monitors. If you really want a traditional guitar cab on stage for the trouser flapping oomph effect just bypass the cab section of the profile in the monitor (alternarive out in the HR video). You will then have the same sound going to both FOH and stage without all the cables and without having to carry your Archon to gigs.
Ok so let's go on with the HR example. The point is that even in this case the only path that involves also the PowerAmp section of the amp is the one that go through the real cab right ? So the FOH gets what's on the HR screen, but since the PowerAmp of the real amp is not going into the HR you're not using its sound right ?
So if I do the same thing with my amp; let's say I'm on the drive channel and I'm using the HR to add reverb and dalay in the loop and then I punt a cab sim at the end of the chain. The real cab on stage is getting the whole path without the cab sim, so Gtr > Archon PreAmp > HR FX in the loop > Archon PowerAmp. Instead the FOH is getting Gtr > Archon PreAmp > HR FX in the loop > Cab sim. Right ?
And of course I'd be in the same situation with the Kemper....
