I am also ready for the new release, but I can wait until its ready. I'm glad I read this post because I did not know anything about the Pure Cab thing. I plan an trying it out tonight. I am Hays by the way and I'll add my two bits on what I think can make a better profile. Get a good mic but be careful. The SM 57 is pretty tough but I have broken a few others by profiling to loud trying to get a good sound. I have learned those things are not very tough. Also, I think its a good idea to take your time. I profile, and wait few days and go back to it to see if it sounds like I thought it did. Your ears get tired pretty quick so its best not to profile and then upload it in the same night. I will also leave the mic where it is so I can reprofile and start right where I left off. I might not even move the mic but perhaps the next profile I will do at a lower level, etc. I do several profiles and over a few weeks I weed out what I think are the bad ones. Then after a month or so, when I have a few I think someone might can use, I upload them.
Since I have been in the modeling world, line6, eleven rack and now the Kemper, I have found that our other gear and how we like to play makes a big difference. Your headphones, your monitors, etc and the room you are in put each of us in our own unusual situation. I know I try some of the other free rigs and they don't fit me, but they may fit someone else just right. One mans junk could be another mans gold so to speak.
I know one thing for sure, its just a fact. What we have available to us all now is so much better than my first amp its just amazing. My dad got me a Yamaha G212 in 1974, at least I think thats what it was. It was great at the time, but actually pretty bad. Real tube amps were pretty expensive back then. We also suffered from no information. Other than Guitar Player Mag, there was no way to know how anyone got their sound and some of the info there was inaccurate. I still remember driving around town one day with one of my friends looking for a variac. We needed one because EVH said in an interview thats what he used to get his sound, by turning up the voltage. We now know he turned it down, but thats not what he said at first. We found one but could not afford it, so I guess its a good thing.
We did not have a nice place like this to come and learn things. Most of us had a guitar, a cord, an amp and we spent allot of time making awful sounds trying to figure out songs.
