verses in E major, chorus and first jam in C major, 2nd jam in E major. click on the envelope filter and add slight overdrive with the first jam (just enough to dirty it up a little, not looking for a lot of boost) Lots of chord soloing incorporated into the scale in the first jam. Don't be afraid to slide in and out of your various C, G and F voicings along the way. Best thing I ever learned about modes is not to limit yourself to the modes. Find your key and move around. From what I've learned, Jerry didn't constrict himself primarily to modes unless a specific part of a specific song called for it. Everything else was free ballin' in the the appropriate key. All the modes connect to one another in the main scale of the appropriate key anyway.
