Ya know, I used to use pretty darned heavy picks, like 1.00 mm Tortex, to try to get as much volume as possible out of the guitar. Then I quit drinking and smoking wacky tobaccy and discovered it was the playing style I had developed from years of playing in, mostly, altered states of consciousness that was the culprit behind my lack of volume. I found that by playing correctly I could use a lighter .73 mm pick and get more volume, better pick control, less pick noise, fewer broken strings, and have fewer picks go flying across the room.
