Can anyone point me in the direction of good lessons or explanations of the right-hand technique of players like Derek Trucks or Luther Dickenson? I've seen Mayer do it as well (as I'm sure numerous artists have). It's playing pickless and using a combination of the thumb and fingers and I'm just at a loss. Sometimes the thumb is working it, then sometimes it almost appears to be a slapping maneuver with the other fingers with the thumb anchored. Is there a specific name to this technique other than just hybrid picking? I see it a lot with slide players. Thanks! For an example of this since my description is probably poor: check the black crowes live at the artists den on YouTube. 12 min in.
