Cool, looking forward to it! And I think you are right...the end result is what matters, how you get there isn't really important.
I find inspiration in a variety of things. It can be a drum beat or an effect or just switching pickups. Whatever gets you rolling and the creative juices flowing!
I may be making a post myself soon. I'll probably revist the backing track I used for my original posting months ago. A new PRS Custom 24 S2 is waiting for me at home, so that should provide some inspiration :-).
