After signing up to AH I just named myself after my own name, Marek. After some thought and thinking it sounded super uncool I decided to name myself GrndZero.
When I was in my clubbing days, and I would visit Poland I would go to this one club in particular, called "GroundZero". This was the hot spot to be back in the day.
However, I noticed that there was already a player called WingZero (What I then thought was a niki noob). So I thought, heck - I don't want to look like a copy cat.
Now when I was in highschool, I use to be in a band. I was the second guitarist on my Richi Sambora Stratocaster made by Fender (Dads gift for my 16th birthday). We as a band were very close. We played mostly Santanas guitar only pieces as we were lacking talent for a lead vocalist. We would spend late nights in Kuwait (Where I grew up) in basements rocking it on, a lead guitarist (now a RL pilot), me, a base guitarist (who now is a professional musician) and other who came and went. Good times.
So there you have it. The extra A is because when I took the name, Santana was taken.
Wasn't hard to guess now was it?
