Vibe not quite as cool and "Wilcoxy" as the open G/C tuning David uses, but close despite that it's done in almost standard tuning (drop D). I've got the instrument tuned down 1/2 step (makes the medium gauge strings a bit more playable). If you can, boost the bass for playback as the gopro doesn't seem to pick it up all that well.
