The only thing I dont like is that when I dial back the volume on my guitar, it does not resonde like a valve amp and get a clean sound. Ive tried messing with the compression and power sagging, but the sound still is not the same.
I disagree completely though I suppose it varies with the profile. Using mbritt's robin ford ODS 100 profile, the amp reacts just about as well as any dumble amp I've ever played through or owned including many of the big name clones. It is much more amp-like in that respect than the axefx. I like the axefx models very much but your description applies way more to axefx than kemper. The kemper seems to be much more amp like in terms of the guitar's volume affecting the tone than any other modeler.
In terms of what I *DON'T* like:
- The effects are generally weak, particularly the time based effects
- no spring reverb
- no multi delays (impossible to get a holdsworth clean sound because of this)
- No univibe
- non realistic trem
- choruses don't compare to axefx choruses
- overdrive and fuzz pedals have way too much gain
- no zendrive
- no editor software
However, in terms of realistically modeling a tube amp, the top of the heap. The real issue it has is not enough CPU horsepower. The single processor just doesn't have the bandwidth to do what axefx does in terms of effects. But in terms of sounding like a real amp, IT DOES THAT REALLY, REALLY WELL!
