Yes, but the waveform doesn't represent spatial movement that way. It's not like one side of the centre line is 'more right' or 'more up'. It has to be unrelated in terms of physical movement through physical space; however, I'm not going to dismiss the pickup's role altogether-- it's just that it can't have anything to do with the movement over the polepieces.

It was just a guess Lunch. However I think that electric signs are caused by disturbances in the magnetic field of the pickups caused by the movement of the string thus the physical vibration of the string is somehow related to the electrical signs and the waveforms representing it.
Now I am really curious what the correct explanation is.

If it sounds good, don't worry about it. FWIW, one of the things that is supposed to make valve distortion more interesting than solid state is the fact that the clipping tends to be assymetric.. its not just string instruments anyway: I have some flute samples that look VERY odd in an audio editor.. they sound great though!

It's a common misconception that audio is symetrical - it simply isn't true. One of the worst offenders is the human voice. If you look carefully, you'll find lots of assymetry in audio files.
Basically, if there is no DC offset, no clipping (either side) and it sounds OK, stop worrying and move on to the next track.

Update:
Did some further tests and all my theories were proven wrong.
I did learn something thou.
The problem only shows up when you play several notes at the same time and mainly very distant notes.
(lows and highs at the same time)
Also learned that when both guitar pickups are on the "problem" really shows up fast.
All this leads to the conclusion that it's some kind of interaction between the notes that creates these sub harmonies that show up on the screen the way they do.
It might be pure mechanical vibrations or maybe electromagnetic interaction between the coils.
In any case I am convinced it's just the nature of things and it can not be "improved".

I have noticed it also with a pristine signal path - its gotta be something about pickups - interesting! I'll bet that if you got rid of it you'd be sorry - one day we'll be paying for an analog style magnetic assymetry inducing VST... (and don't worry so much about gain!)
