Second things first. The password information is in the review. It's so he can offer the discount to the Guitarnoise folks. It's guitarnoise/approved
Mitch, Kirk's method is a series of connected mini-patterns, this is one unified spiral pattern and methods of moving about in that pattern. Also the pattern is linked into chord structure and progression in a way that takes a little while to understand, but once you've got it, it's a cool way of looking at things. Actually, now that I think of it, I just had another Eureka moment courtesy of RSoG....Kirk's method isn't a series of connected mini-patterns, it's just one.
...one other major difference, with the discount it's less than half the price.
I talked to Fred about the very subject of putting up sample pages. This may sound like a crock, (but keep in mind that I'm not making anything off of this), but if he puts up on the page anything more than a basic sample he is giving the whole thing away. It is that simple. If you've already got a method you are happy with, like CAGED, maybe you want to stick with that. Or maybe RSoG will do what it did for me. It really helped me seeing a unified fretboard. It's almost like seeing a piano keyboard. I can tell you immediately where a C is anywhere up or down the keyboard. The C is just the one before the two black key set. If you know the root, and you know the basic pattern, you can pretty much play it anywhere on the fretboard with just a little practice.
Let me put up a warning here, don't let fact I keep calling it simple lull you into thinking all the work is done for you. Also don't dismiss the concepts here just because they are that simple. If you take the info here and plug it into what you already know you will start to see relationships you never knew existed. To me it's like this: you've been driving the same way to work every day for years, one day you can't merge when you have to and you find a new way to the same place but it cuts 15 minutes off the trip. Now suddenly you can use that same new found path to go a whole bunch of new places, not just work. You scratch you head and think, "why didn't I know this was here? It's obvious this road should connect those two. Wow, I wish I knew about this path years ago."
You can see a brief sample of style, but not much in the way of content here:http://www.rosettastoneofguitar.com/rSog_sample1-1.pdf
I really do believe if you spend a few nights working on it, seeing the pattern, playing it, trying to understand what he is saying, and integrating it with what you already know...within the week you will have it mastered and wonder why you didn't see it all before.
This isn't one of those big bold, money back guarantee sites, pitching the same old stuff repackaged. Fred put a lot of work into it and he helped me see relationships on the fretboard that I'd never noticed before. I really hope that if you buy it you get that same eureka moment I did.
Just to compare bang for the buck for a moment, this DVD is less than I pay for one lesson and I got a lot more out of it.
One more thing, I got a free review copy. I get a lot of free review copies. You want to know the number of times I've turned around and paid for the merchandise anyway? Once, for the Rosetta Stone of Guitar.
