Now that I have a resonator for exactly 12 hours so far, my slide blues in open G is better than awful. It's actually bordering mediocre and I think in a week or 2 it may actually be considered decent. Hearing this instrument, it'd be a shame to not learn some bluegrass. That stuff is just a whole other world and I have no idea where to start. Who can turn me on to a good method book or dvd??? I don't want to get dueling banjos deliverance good, but would like to at least be able to get the foundation of the genre.
