Ok so here it goes...
I have a friend who after having me over to his house to profile a couple of his amps bought a Kemper for himself (Powered Head). He love the fact that the profiles sounded almost identical and that the feel was there unlike other units. Once he received his Kemper and started playing through it, he noticed that no matter how hard or soft he hit the strings the volume wouldn't go up or down like on his amp. I asked him to bring his Kemper and cab over to my house so that we could do some experimenting. I plugged my Kemper to my studio monitors and he plugged his to his 2x12 cab. Both Kempers were reacting the same way so we knew the speakers weren't the problem. The amp profile would start to breakup the harder you hit the strings but the volume would not increase as expected. So we started digging into the parameters to see if we could figure out what was causing this behavior.
After a lot of tweaking using his equipment, we figured out that by turning the compression in the Amp block all the way down and the Volume of the Amp (in the amp block) all the way up the volume of the profile would increase or decrease depending on how hard you hit the strings. Talk about real feel now, it was incredible, the volume and amp breakup was happening by how hard or soft you hit the strings. This is most noticeable in a clean to semi-distorted rigs, but even noticeable on heavy distorted rigs.
The next thing that happened was very unexpected. I decided to make the same changes to the Amp block of my Kemper which was connected to my studio speakers to see if I got the same result. What happened was that I got the same result PLUS my studio monitors almost sounded like his CAB in the room. We just looked at each other like what just happened. I have two M-Audio BX5's and they sounded like his 2x12 cab. I don't know how the Amp block volume works but let me tell you, the Kemper now sounds like I am playing through a real CAB in the room. I think this is something we all crave but haven't been able to accomplish with digital units. Maybe it has something to do with the Amp being more in front or present in the "profile" which makes it sound like it's right in front of you. I don't know how this will translate to the front of the house or in a recording but will find out this weekend. However, I am loving the sound coming out of my studio monitors right now.
I would like to know if anyone else has tried this or is willing to try it and give me some feedback as to your experience.
