First off, I'm not here to rag on Kemper or anything, so don't get offended. I absolutely love my Kemper, and one of the greatest, most surprising things about Kemper is that I've never enjoyed playing vintage style amps so much. I'm a shred/rock/metal kind of guy mostly, so I don't care too much for old Fenders and pretentious boutique amps. However, some of the profiles are simply outstanding.
Little Walter 22 & 50 - World class profiles, work great with external overdrive pedals and effects, really great dynamics and pick response
Vab Clean & Lead - WOW! Such outstanding sounds. Extremely authentic, amp-like in feel and tone. I REALLY like these so much I wish I could buy the real deal.
JCM800 - Not sure if this is the Michael Britt one or another, but one of the JCM800 profiles really nails it.
Suhr Badger 30 - I used to own the real deal, so I can say with some qualification that this profile is very good. There are a few, not sure who made them, but there are two I particularly like.
Fender Tweed 57 and Champ - Really great job on these. Love playing them. The Champ has that small amp sound and everything. Very cool profiles.
Friedman Dirty Shirley - There are a couple, but there is one that is really good and responds very well to gain changes.
.....
Now, having spoke on behalf of a few choice profiles, I find that most profiles seem to be guys just dialing in amp the way they like rather than finding an optimal combination of settings, volume, etc that makes it easier to personalize for people who use the profiles. Maybe I'm wrong here, but I've been doing a lot of profiling lately. I've read how guys do it, descriptions of how the commercial profilers make theirs, youtube videos, etc. It seems to me that if you take a usable, base sound into consideration, it takes 5-6 profile attempts before getting a profile that works really well. It's so much easier to just dial in a sound I like because that only takes one take. It's much harder to create profiles that are more workable.
I'm still a relative newb, but I've been rather spongy in my quest for learning the Kemper, so I think there are a few little things that can be set to make profiles more universal but not generic. Direct profiles + IR's seem the most satisfactory and versatile to me half of the time, but the other half of the time it's just a combination of an amp + cab personality and how mindfully the profile was done that comes together just right.
Some of the profiles I really wanted from amps I used to own or always wanted were:
Friedman JJ-100
Hiwatt DR103
Hiwatt Custom 50
EVH Stealth 6L6
Fender Supersonic 22
Engl Invader
It took some digging around the Internet, and most of the JJ profiles were not so great. Then I found about 5 that were really good, so I think it's fairly well set on the JJ now. I've found a lot of Hiwatt profiles, but nothing so far has managed to capture some of the magic spark you get from a real Hiwatt. There are a lot of EVH5150 profiles out there, and other dude sound far better playing them than I do, but I much prefer the voicing of the EVH 5153 Stealth with 6L6. I didn't care too much for the newer EL34 version of it. I found a commercial profile pack for it, but not sure if it's worth buying.
You'd think there would be at least a dozen great Fender Super-Sonic profiles, but I have yet to find a Super-Sonic profile that really captures how great that amp can sound and play. Lastly, there are the Engl profiles. So far they've been OK, a few have sucked, but I have yet to find a really, really good Engl profile of the Invader or SE, and have not found profiles for the Artist edition which is almost a must-have Engl profile.
Anyway, I'd really like to find some good profiles, of these amps, so if you get what I'm talking about and know which ones to get, I'd appreciate that very much. If you disagree with my assessments or opinions then fair enough. Like I said, I have 99% great things to say about Kemper.
Also, has anyone tried the Dr.Z profiles. One amp, the EMS, was one I really looked forward to. However, on a Youtube review, the guy basically said it's just OK and only good for gain if I remember correctly. In any case, I'm not a vintage amp kind of guy, but I love Dr. Z amps. If anyone has bought Pack 1, I'd like to hear what you think about it.
