I found some drum loops at:

I've been riffing in Drop D all week and I'm really liking it. I recorded this simple blues progression and then this is the solo over top.
I was using a BYOC tubescreamer for the dirt and then my pickup booster for the lead boost.
amp settings:
volume - 7
fat - on
treble - 6
bass - 6
mid - 7
master - 2
reverb - 2
