There are lots of different kinds of picks. Finding the right pick for you can make playing much easier!
Thin picks are great for strumming chords. They bend against the strings while you strum and have very little resistance. The downside to thin picks is that they bend and have very little resistance! This means they aren’t very good for doing fast single note runs. If your style is mostly playing chords, this could be a good fit.
Medium picks still have some give when you are strumming, but work much better for hitting individual strings. These are great when you are strumming chords as well as picking some individual notes out of them.
Heavy picks don’t have any give at all and that is exactly why they are perfect for fast picking. If you want to shred and play the fast lead parts, heavy is the way to go!
Besides how stiff a pick is, there are other factors you may consider. Larger picks are easier to hold on to. Smaller picks are more maneuverable. Sharp picks can dig into the string faster, and dull ones have a much more rounded tone. Try them all and find the one that’s right for you!
