Hmmm, I've been playing for like 7-8 years I believe, and I still don't know If I can. I was never really bothered to learn shredding. I mean, I can play a bunch of death solos, well, all that I've attempted anyway, but have never really tried any Malmsteen or Gilbert. I like to think I'm fairly accurate with my alternate picked leads and arpeggios, butI never was very accurate at all until about 5-6 years into playing. i could play easy leads up until then, but I was a little sloppy on technical and fast stuff, ala vai. Things got better though after I learned Tender Surrender and For The Love of God. I can now get through these fairly gracefully, though I do like to add my own little nuances to certain phrases rather than doing it note for note.
But in regards to the two year question, after two years of playing I was probably working on Guns and roses solos, skid row (slave to the grind) Ugly kid joe, tons of slayer songs and leads. Badly though, if my memory serves me correct!
