I was wondering what technique is being used in a lick in the song wagon wheel by darius rucker (or Bob Dylan I should say).. If you follow the video i attached it starts at 0:21 and ends at 0:24.. It can be heard in the right speaker. I think its a steel guitar bend type technique? I'm not sure...
Sounds like they're just doing double stops using fingerpicking. I could be wrong though.
