Ok now I have to get involved..... :p

I think I see what you're saying.....you want to know if there is a way to learn all the different modes of every key there is? You want to learn an easy way to stay in Amaj all the way down the fretboard and all that jazz right? There is no easy way to do it which is why I just go with what my ears tell me. It is a huge investment of time to learn [U]all[/U] of them be tween minors, majors, and the rest it'll take years. A lot of musicians shy away from theory as much as they can get away with. It is imperative to learn as much as possible but not always enjoyable or easy. So in response to your question....No, there is no easy way to do it just practice like almost all things in guitar. Oh besides using reletive scales which is usually how I go about it. Usually just Major and Minor but it's the same for all keys and counting frets is part of the strategy but that's about all I got.
