Thanks again Jeff...
At around 3:38, about where the outro kicks in, I start plucking harmonics - with stereo chorus - pretty much the same notes that I start the tune off with. The delay in meeting new tonalities with the harmonics is an intentional effort to hype up the tension before the resolution, kind of like enjoying the cold before stepping into a hot bath; I guess its not working as I planned. Beef up the bass to provide a more solid foundation for the chords makes sense.
XLR: Thanks for the listen. Yes, there are a few less than pitch perfect notes there I must agree. I'm pretty fussy with the tuning, so it is my fretting of the notes that is responsible. I didn't use vibrato to compensate for not hitting the sweet spot, though I was hoping this would give the tune a certain "authentic" quality - but I take your point.
