Great tone--feels just right!
When I was young I used light picks. Then, as I matured I switched to medium picks. I just happened to receive one of these extra-hard as a freebie from Strings and Beyond in an order a year or two ago. It's just been lying around without slipping into the lost pick dimension--I guess because I didn't use it. Well one day I saw it lying there looking all yellow and clear, and so I decided to give it a try. We'll, I was pretty much immediately hooked. The sound is different from the regular picks I use. It just sounds good. And, it feels great. So, I've been using them ever since. I don't know what they are made of--I suspect it is polycarbonate. But, whatever it is it provides a nice strong smooth tone.
Very Nice Feel
Looks Great (transparent) (see cons)
Sounds Cool When You Drop It Onto A Hard Surface (it kind of tinkles).
ConsEven though the transparency is cool, it makes it easier to overlook (and lose) on many surfaces.
