In the beginning i played 4 hours every day, now i play like 2 hours (sometimes more, sometimes less)
I play pretty much what i feel like doing for practice. Mostly just learning new songs from my favorite band and stuff. sometimes i practice my techniques. sometimes i go through some lessons here on the site which adds a nice variation to my routine (i should do more of that)
Im not really in to the whole scale ''up and down'' thing. I think it gets pretty mindnumbing quick. And since my playing style is basically 80% based on Slash's playing i don't feel the need to learn full on shred guitar, and if i wanted i would not know where to begin...
