So I did get a usable take:
https://soundcloud.com/hieronymous-seven/rays-of-sound-demo This is just a demo - I think I am going to cut the two measures of bass-only at the very beginning and rerecord the filter sweep in just the 4 bars with the filtered drums, but I did want to try it this way.
I did end up doing the neck pickup clean (panned slightly left) and the bridge pickup through the Budda distortion (panned slightly right). I recorded some free playing, then did a couple of passes on this tune. Erased one I maybe should have kept, but the next one was ok - punched in another take from the key change because I messed up. By this point I could tell I was getting a little tired (I'm out of practice!) - thought I had messed up my settings between the two takes and was thoroughly bummed but then realized that I was confused and mixed in an earlier completely different take! Phew!
