Take it easy on me guys, I'm a guitarist, not a bassist.  I was just figuring this out 
my newbie bassist of a brother and figured, "hey, why not actually

submit something to this site for once?"

Drop D

Guitar only

This was pretty fun to do actually, it made me realize a few things about my music.  And 
subs.  Anyway, if you see/hear anything out of place, let me know so I can fix it.
