Hi Nancy: You can request a non-premium tune for John to work on developing for you and be placed on his list of non-premium requests or request a premium. Either one can be best addressed by emailing him at firstname.lastname@example.org
I could record the way I play it and play it slowly in an audio (not video) if you think that would help, but I just don’t have the time lately to write it down and I’m not set up to do video just audio. I’d have to talk you through it the way I play it in Bluegrass style.
I can’t speak for Fiddlewood (Dave), but if he has the time he might do it. It’s a busy time of year for him, though. He’s an excellent teacher and has helped a lot of folks here on the forum. He would do a video where you could see where he puts his fingers.
