I’ve been trying it myself for a while, picking up hints and ideas from this amazing artist - this was 5 years ago, but it’s one of my favourite pieces of musical magic! My favourite performance was with JB showing off his young protege Bass player Tal Wilkenfeld but this is a very close second!
Just out of interest, that’s a Squier Affinity Telecaster, unmodified just set up the way she needs it!
