I know it has been discussed here before. But there's something that I don't quite understand, let me explain my case.
I own a Kemper since barely a few days. Love it, BTW.
However there's the Aliasing problem. I know this is an inherent problem with converters, but I don't totally understand where it happens.
Is it my guitar that introduces higher frequencies in the AD conversion? I don't think so, I don't hear anything on clean sounds, but it could just be not apparent.
Is it the processing that - in the case of very distorted tone particularly - generates harmonics higher than the Nyquist frequency?
The thing is: I am experiencing this with all heavy profiles. Most of them show it only on really the highest notes (say, 20th fret E string) or some harmonics, others are apparent even starting from 14th fret on the G string.
On the other hand, I profiled a preamp - which did generate aliasing when recorded on my PC, so we're really comparing apples with apples - and very surprisingly the resulting profile shows no sign of aliasing!
Why do you think that happens?
