That's an awesome demo. Big fan of KPA. BEST recording unit I own!
Now the trick is getting that emulator gear to sound the same LIVE. Problem for me is whether the AxeFX GSP 11R etc or KPA is used, those FRFR speakers or even through original cabs the tube amp just works different.
I know a lot of guys are getting used to modelers going through powered speakers or even some with power amps and cabs. I've tried all the above. When it comes to stage power and feel I just don't get it from these emulators like I do from tube amps.
I saw many of the videos and while it might seem cool to some to jam with a PA Speaker and use cab IR's, place a 4x12 and a Recto up there on the same stage and we'll see which is more the performing tool.
I've tried the good powered PA speakers, the SLA's every modeler user was feverish about. That all changes every time something else is the trend. They don't work the same. After a while I got a little tired of buying and selling powered wedges, different SS rack amplifiers.
One day at GC my wife says, "is this the last thing you are going to buy for those computer amps? why not just use the three amps you always liked? I don't get why you want the computer thingy to sound like the amps you already own? If you ask me its redundancy!!"
Maybe she's right! It doesn't stop me from buying stuff I think I like though. LOL! At least she's a good sport about all this!
