Thanks for your answers. It's really beeing helpful.
Thanks @ JimK. That's really cool, i'D never have done it that way myself, but i goes that's how to go with it!
Timm99 ... i do own the Flea-DVD already, i'm already a huge Flea Fan and draw some inspiration of him.
I don't really like books and Videos. I got some really good books at home about various topics, but i never really use them "properly".
I don't want to copy Rocco, or anyone else. I just want to draw inspiration from his way of playing and "emulate" (that's the word Flea uses) it to my style.
On the way to get my sound i've done it like that. I tried to copy the sound of Flea, but put it in another direction.
I'll be sure to check out more of Jacco's Stuff.
