I know you and some of the other guys in Periphery like thinner picks, I just wondered what the reasoning behind this was? Especially in an age where the thicker, smaller picks seem to be most popular. Recently I've been trying the .60 Dunlop TIII and I'm loving the 'thwack' it gives.
We find that thinner picks have a juicier attack especially when palm muting, and also function a little like a compressor in that they bend more when you pick harder, or when you're picking on the thicker strings, making the notes more even. Really technical stuff can get a bit messy though, in which case I swap back to a thicker (but still no more than 1mm), smaller pick.
