one thing I have noticed, is that it is NOT how many years you have played, but rather WHAT you practice, and how much you play EACH day. I know several guitar players who have played at least 30 years, and they still kinda suck, if you know what I mean....same pentatonic scales, lousy amp tone, out of tune, etc, etc. However, I have witnessed guitar players that after a year or so of heavy playing (like 8 hours a day, min), started to become very accomplished players. I saw a fair amount of this when I was at Berklee, in Boston, Ma. Especially foreign students. After a couple of years, they were starting to become monsters on their instruments. You see a major difference in CHOPS, in the player who has spent at least a year or two and played every day for at least 8 hours+. ....and those that constantly jammed with their friends, day after day after day...their ear developed quickly too. ...and then there where those that exceeded this, and were basically completely unfriggen unbelievable at their instruments...at least to me.
