Ultimately I think we’re on the same page.
Here’s the thing:
Where longer scale guitars are concerned, that 1-2-4 option goes out the window, especially where covering Paul’s licks are concerned. If you use 1-2-4 for some of his licks, you will be pulling notes sharp/flat like crazy. You’ll be playing very fast, but you won’t be playing the notes you think you’re playing. An example would be 8-10-12 on the 6th string; on a 24 fret/25.5" guitar. If I gun it as fast as possible (150-160 sextuplets), my hand starts pulling the notes into 9-10-12. If I switch to 1-3-4, it goes away. The posture is able to be maintained, and the notes stay as 8-10-12. I’ve tested this many times while recording.
My point is that you can’t adhere to EDC principles if the position you’re playing in doesn’t allow for 1-2-4 while staying in tune. This would be the only way I know to “break” the concept of an EDC.
Paul suffers from this on both Intense Rock videos. One of my alternate picking thread entries covers that. It doesn’t surprise me though, Paul always played different scale guitars and it might just be a force of habit or muscle memory. His old email list/database manager once described a room with guitar after guitar strewn about, of all brands, types, and scales. It’s not hard to imagine that Paul might be playing all sorts of guitars and bring fretting hand habits from one guitar to another, where they may not be as efficient.
I think if you wanted to play Paul’s stuff as fast as humanly possible, you’d likely have to get a similar shorter scale guitar that Shawn used which makes 1-2-4 possible without pulling notes sharp or flat.
In short I think @Tom_Gilroy we are in agreement, I would just make the addendum to your EDC post about utilizing a guitar similar to Shawn’s for his sort of playing. Based on my research and own experiencing in hitting high speeds, it seems a shorter scale length guitar is the recipe for hitting the fastest pitch-perfect speeds possible, precisely because it enables the usage of 1-2-4 where you would otherwise be forced to use 1-3-4 on longer scale instruments.
Maybe we can take this to private message @Tom_Gilroy. I’ve been meaning to get your feedback on some of this and I don’t know anyone besides you on the forum who pays as much attention to fretting hand strategies as I do. I am also aware of how insane things are now, so if the timing is off, perhaps in the future.
