Can't really think of a stupid mistake now...I used to hold my pick in a different way for years and years than I do now, kind of flat between my thumb and the palm of my first finger. I think Todd called it "classical" at some point...there seems to be a classical position for everything, right
Back to the topic before this gets outta hand...anyway, the pick would hit the strings with the flat side, which isn't too bad when you play chords. But it gave me trouble when I wanted to do AP a bit faster. So I switched to the "shredder grip" 1,5 years ago and use it all the time now. Just lately I discovered that players like Matthias Jabs use their pick in a somewhat flat position and can still play really fast...
Okay, not really a stupid mistake, but something I did for years that held me back in my progress.
I know the pick postitions you mean exactly.. and yes, Mattias does appear to hold his pick like that
What is the shredder grip? It sounds impressive!
If we told you it would put your life in danger...
Nah, I think he just means holding it between the side of your finger and your thumb.. the 'correct' and 'normal' way
