I've played guitar for many years, but for the last couple of decades it's only been casual noodling, often improvising with music I have on in the background.

I've played guitar for many years, but for the last couple of decades it's only been casual noodling, often improvising with music I have on in the background. I read music, but slowly and reluctantly so have only a weak association between note names and sound. But I have a strong fretboard/sound association that is some sort of pitch memory. I can jump straight to a note, or if not to it, I'll be off by a fret (semitone). It's more accurate wiht a quick intuitive attempt - if I pause to think I'll often be further off. Jumping straight into playing with/over something I hear I'll nearly always start on the right note. What pitch memory I have is very clearly learned, and I suspect it could be developed it were a priority.
