Hi
How you tune up will depend mostly what type of music you intend to practice. I started lap steel back when it was called Hawaiian guitar. I was twelve. Hitting eighty this October, so have been at it for a while. "G" tuning of course for Blue Grass, but will also work on other stuff,especiolly if you make the fourth string an "E", giving you a G6 chord or Em chord. Hawaii when I was there favoured a C6 tuning......Good luck...Hank
