Hi,
Most of my life, I've used Standard EADGBE tuning. To expand my horizons, I've experimented with several alternate tunings, settling on "Open G", DGDGBD. Why? It suits my finger picking style and the type of music I like to play. I've really gotten into it, and now use it exclusively for all my arrangements.
