Sore fingers. Big grin.
I've basically been going through loads of rigs (factory content plus I got a load of Amp Factory rigs). There are an awful lot of sounds to like in this box. I've hit the 'favourite' button more than I should have already. How can you have 80 favourites when you haven't been through half of the rigs yet??
I love the free Morgan 20 profile - that one is amazing. Loads of the Amp Factory ones are great (loving the Tone Kings, Vox, some of the Fenders, some of the Marshalls. Everything really :)) Loving the dynamics - just playing any of the clean+ profiles is great fun.
Still getting used to the noise gate - I've not used one in years and, whilst it is very good indeed, it's taking me some getting used to.
I've found it pretty intuitive to use - the things you want to adjust most all have a knob or button. Other things, so far, have been easy enough to find in the menus. I daresay there is a lot more weeks of learning to be done and I won't know what I'm missing until I read the manual more carefully or stumble across a great tip on here.
I like the chorus, phaser and flanger - all are really good IMO. Also love the reverbs..... Like most other folks, a spring and a plate would be nice additions. I have a Strymon Timeline, Flint and Mobius and I had planned on putting them in the loop but so far I've been enjoying the Kemper versions so they can wait! I like the trem on the Mobius / Flint moreso than the one on here BUT there are a lot of parameters to tweak here that may get me close...... There is a really nice harmonic trem on the Strymon kit that almost sounds like a phaser crossed with a trem. So I may try doing a phaser and a trem here and keeping both subtle to see how that works. The delays are good but on the Timeline, the 'labelling' makes more sense than here..... I'm sure you could make a tape-style delay here with tweaking. On the Strymon, you just select dTape and you're there.
I've used it via my stereo monitor speakers and also was pleasantly surprised at the fact that it sounded good through headphones. Didn't see that coming.
I've used it with one of my home-made pedals up front already. I recently made a clone (well, as best I could with the germaniums I could get) of an Analogman Sunlion. Which is a 2 in one pedal with a tweaked fuzz face on one side and a tweaked Rangemaster on the other. I'm pleased to report that the Kemper behaved exactly as I would hope..... And hitting a hot AC30 with a Rangemaster was a lovely thing to do - seemed to work better than using the in-built treble booster.
I haven't even thought about profiling yet..... I only have 2 valve amps but, at some point, I will have a go and (if they come out OK) I'll pop them on the exchange. One is a Matamp C7 (which is a lovely little 7 watt valve amp) and the other is a kit-build super-clean thing based loosely on a Fender Champ circuit.
Things I struggle with - rig management already. I can see why people want the librarian so badly. Also, why a USB stick? Why isn't it possible to just plug a USB cable into your PC for transfer of rigs / software updates etc?
So overall a success so far
