any1 knows such sites??

Youtube.

Search "guitar lessons"

gee thx, but most of them are total craps

idk what you mean. I find most youtube lessons quite effective. What type of guitar/music are you interested in playing? Just saying you want to learn guitar is very broad. It could mean electric, acoustic, or classical. Then once you decide the type of guitar, you should further narrow it down by genre. Typing metal electric guitar lessons into youtube will provide better results than for example, just typing guitar lessons.

right now i got some problems wits pentatonic and like most of this soloing stuf. i found (on yt) a german guitarist zibi whatever, and his sweeping lesson just roz, but all others (like pentatonic, which are the main problem) sucked :/
