CAn Someone Give me a good picking tip

Regarding picking styles, there are primarily 3 different types of picking. The most popular and widely used form is alternate picking, which is, of course, as it sounds: every note is picked up/downup/down. But another way to pick that increases facility and speed is economy picking. When using economy picking, things are simplified - when switching strings the stroke need not be the opposite of the last stroke, but it can be the same. This is hard for me to explain. Use the search function in the toolbar and search for picking or economy vs. alternate, etc...

I've always been a proud user of economy picking because it makes more sense to me. However, the decision on what picking style to use comes down to you. I cannot tell you that this style is better than anything else, but it does work for me. Experiment, and see what you like the best. I know plenty of shredders who use econ., and plenty that use alternate.

Most of what you learn about this stuff comes from experience. Play around with all this stuff as much as you can, and the answers will become clear to you.

Another thing you can do is alternate which direction you begin picking a scale. For instance, most guys will start a scale with a downstroke and then alternate pick the rest of it.
Instead of doing that, start the scale with an upstroke and pick every note the opposite of what you'd normally do.
If you spend half of your time practicing in reverse like this until it becomes natural, you'll find yourself not even noticing anymore which direction you're picking in. That way you aren't always limiting yourself to starting leads on a downstroke for instance, or worrying about getting lost in the middle of a lead and having to suddenly reverse direction.
(hard to explain in words.. hope that makes sense)

low Estring:
1 2 3 4
v ^ v ^
repeat in every position possible and on every string
v=down stroke
^=upstroke
start slow with a metronome and slowly increase speed
use heavy heavy picks and use your wrist, not your arm
variate it to your usage invert the picking pattern or switch the fingering get innovative

try circle picking....you gotta hold the pick at an angle to the string instead of parallel to it. Then you make a small circular motion with the pick, but your wrist shouldnt move, only your fingers holding the pick. It takes a while to get but it can be twice as fast as alternate picking when done right.
