Eddie,

I STILL can't make my brain stop using the fret markers.


I do the same, primarily because I’ve never had a guitar without fret markers.

That being said, what I do if for example I’m using a capo on the second fret and using a C position, I think in terms of C when I’m playing next to the capo but I switch to thinking in the key of D when I head up the neck.
