This is a refinement of the jazz III picks. When faced with the company logo upwards, it slips more easily across all strings, than when faced with the Eric Johnson logo upwards. It is shimmed or trimmed at a special angle.
It's more softer than the black ones, and their regular "red" ones. As for getting any Eric Johnson sounds out of these, it's totally moot. If you're already used to red Jazz III picks these may give you a smoother cross section when it hits the strings and not so much resiliency. I e you don't have to pick or dig in as hard.
