Non symmetrical waveforms

Hi, I'm just starting to record my bass lines in my laptop and I've seen a certain tendecy in my recordings, the wave form is more accute when going down than up. I'm just wondering if this is expected for a bass guitar wave form because when looking at the guitar recording looks to me as more balanced. It might be that my audio interface is not working properly or just that I'm looking for an excuse for my bad playing :-)

I've included a image of the wave form.

BTW I'm using Cubase Essential 5 with a M-Audio MobilePre USB audio interface, this is on Windows 7 64.

Thanks!

Johann

Some information I've found so far, BTW is called "asymmetrical waveforms":

"DI's Bass guitars can produce asymmetrical waveforms because -while the string itself may vibrate symmetrically- the pickup will likely have a tendency to see the 'nearer' pole of the wave strongly than the 'further' pole, as a result of diminishing magnetic field strength with distance. -Pickups closer to the strings would be expected to exhibit this characteristic rather more than pickups mounted lower (and thus further away from) the strings."
