Gary- Try Em7 (022030) or (022033). Having the 7th of the chord (open D string) down low sounds a bit muddy to me.
I like to put it on top, like on a snowman. The root (E) is the body, the third (G) is the torso, the fifth (B) is the head, and if it's a seventh chord (adding D), the snowman gets to wear a little hat.
If the snowman is into jazz and we add a ninth (F#) and he'll never melt, cause he's cool, man... yeaaaahhhh.
HARMONICA KEY ON TOM PETTY SONG(HELP!)
I hate to bring this back up, but was the correct answer to this question to use a "G" harp or a "D" harp? That "when blowing out it sounds a G chord but might actually be a D harp" line threw me. I may have to try to learn this one harmonica part since we can never count on the harp player to show up and he's never actually listened to the real song to figure out the correct part. We play it all the time without him but it would be nice to at least try to figure it out.
