Going back all the way to 2008...funny story.
In 2007/8 on TGP the Fractal trolls trolled the Axe-FX Standard every day Ad nauseam as the greatest piece of gear ever that sounded "exactly" like a tube amp.
I had been in a friends studio and we had mic'd up his Marshall TSL602 with a Drivemaster pedal in front of it and recorded a clip.
So I posted the clip on the TGP and asked the Fractal 'wolf pack' to record the same riff on my clip using the Axe-FX Standard...after all it sounds exactly like a tube amp.
So a few of the Axe-FX boys attempted to play the riff, not one of them could nail it, and their tones were nowhere near not even close...all kinds of excuses like my wife and kids are waiting outside in the car so I just recorded a quick attempt.
In 2011, rumors were spreading on TGP that some guy named Christophe Kemper had invented a machine that could Profile tube amps.
The Fractal wolves went berserk, including Cliff himself, impossible, Vaporware, it's never going to happen, Profiling is just EQ matching, it's never going to release, it will never sound like the Axe even if it does release, blah blah, non stop for the entire 2011.
When the Kemper released in December 2011 guess who had one of the first Kempers in his laboratory/workshop?...Cliff. ...and all the updates and new models since then have attempted to equal the Kemper feel and tone.
Moving on, 11 years later in 2019 my friend who recorded the original Marshall TSL602 plus Drivemaster clip (in 2008) decides if the Kemper can Profile his live rig, the same TSL602/Drivemaster and replicate that particular tone he'll be convinced and buy a Kemper...which he did!
This is the original TSL602/Drivemaster clip/riff I posted in 2008 on TGP now recorded in 2019 using the Kemper Profile of that same rig.
