No doubt because of my part-Sicilian DNA and always living in humid climes, I've never had this problem: Maybe it's the olive oil and garlic intake . . . . . . . I'd loved to have been cold on an outdoor gig, I seemed to only do outdoors is summer, where cold was NOT the problem.
I always wondered why I could never get a sharp attack with my fingers (more pick-sounding) and other guys could. Then I read one of Bob Taylor's articles where in the course of talking about the variables involved in tone, he mentioned 'bone tone' that they certainly couldn't account for when voicing their guitars: Some people just have bonier or fatter fingers, and this made the difference. They just had no way to account for the individual physiognomy of individuals' fingers. No wonder this guy has made such an impact in acoustic guitars.
