I'm at the very beginning of learning to play guitar, and I recently needed to buy some more picks. This was more complex than I was expecting, since there are apparently many different weights of picks available.
I've gotten the impression that people generally categorize picks into three types: thin (or light), medium, and thick (or heavy). However, sometimes they're classified by a specific thickness (0.60mm, etc). As an aside, is there a particular thickness threshold for each of these types?
I ended up buying a few picks of different thicknesses, just to see what I liked, but I'm curious if there's a particular reason to use a certain type. Do the different picks produce audibly different sounds, or are they useful for different styles of playing for some reason? Or is it just something that comes down to a personal preference for which feel you like?
