As a long time forum reader and new Kemper owner, I agree with being a little bummed out if my goal was to completely replace all of my Amps/Preamps with the Kemper with no loss. I was defintely hopeful that would be the case but probably it wasn't realistic in my head. I haven't had a ton of time to play around yet but overall i'm quite let down. I've been reading the forum, saving up and listening to every clip that can be found for commercial profiles. I picked up a lot of profiles through the Black Friday/Christmas deals, so i have profiles from all of the big names (except Bert), but i'm having little joy. I need something that is flexable and works well through headphones as well as monitors and cabs. Late at night when playing with headphones, the sound is terrible. I can barely tell the difference between cheap software modelers and the Kemper. I currently have Sony MDR7506 as well as Audio Technica ATM50's, the Sony's have too little bass and the AT's are a bit boxy/boomy. When playing through a cab i also notice a severe lack of low end and punch compared to say my Egnater MTS setup (or my Peavey XXX). I have a Marshall 4x12 (75 watt) and a Bogner 1x12 (v30). I really, really wanted this to work but in less than a week i'm already researching alternative solutions, such as a Mesa Boogie Mark V 25 and the new Torpedo Captor direct box to connect and use their Wall of Sound or some other IR loader (i'm not crazy about their Cabclone output, at least in clips) for silent recording and still have the big sound when playing in the room. If money were no object the tone i'm searching for i'd say is the Steve Stevens Friedman, The Petrucci Mesa Boogie c+ and the Fuchs Blackjack clean tone (i already have a vintage fender princeton but it needs some work). Since this is all very expensive i was hoping to get it all in the Kemper. Honestly after switching through rigs looking for a sound everything starts to sound very similar.
While the sound is better after i record and listen in the car say, but it does not sound like the clips i hear of the same profiles from the commercial vendors. I'm mostly using an Ernie Ball Silhouette Special (with the stock Humbucker and Lindy Fralin single coils) and an Ernie Ball Axis. I haven't been playing much in many years and I was really hoping this would spring board me back in to it with a ton of enthusiasm, but instead it's sort of draining it.
As far as what brought me to the Kemper, I like a lot of the clean tones (though even in clips it's really hard to find that sound i'm looking for, i'd say the closest was Andy's Lazy J collection..which i own), Britt's /13, Tonehawk's demo. For distorted, Jay Wud's demos of the Rectifier and Orange from Reampzone, Top Jimi's brown sound collection, Sinmix's Be100, MixBerlins 5150/Rectifier and Guido's lead tones. I have a lot of those, but not all, i stopped purchasing anything until i sort out my issues. In fact I like the free Tim Owens Be100 and someone else's CCV as much as any of the commercial distorted tones..but don't satisfy at least while playing.
Before i give up, i want to try to Profile some of my setup and see how it compares but i don't currently have a direct box to try and direct profiles. Studio profiles are a bit trickier since I have 2 small kids and no sound proof rooms.
