A Heck of a Great Plectrum
If you're into solo plectrum guitar pieces (see Rob MacKillop's YouTube channel for some exemplary performances), this is your weapon. The grip is superb, seems almost to stick to the thumb and finger. And it feels weightless, kinda odd for a pick as big as this. Also works for bluegrass, swing, Gypsy, etc.
I have to wonder why this thing costs so much - it's more than other Wegen picks, and I'm one of those people who lose picks like crazy, so I really cuss when I lose one of these. It's a fine, fine pick, however.
