here's a little chromatic'ish exercise that I've recently started using that's helped me in some different areas. It's nothing special, but it works on both 'inside' and 'outside' picking.
e----------------------------------------------------8-567---5678-
b----------------------------------------8-567---567------8-------
g----------------------------8-567---567------8--------------------
d----------------8-567---567------8--------------------------------
a-----8-567--567------8--------------------------------------------
e-567------8--------------------------------------------------------
I'm too lazy to write out a descending part but you get the point. Of course it's straight
alternate picking in a 16th note pattern, but mixing it up as 16th note triplets or quintuplets can be fun too. I'll load it up as regular notation w/ tab with some other stuff as soon as I make some more up...(I'm sure it's been done, but it's new to me).
