Same here. People will say that I know so many songs. Truth is that there are usually only (not always) 4 or 5 bass notes played in any song. You just have to know the order. The bridge or turn may have a minor chord, Lot of songs are similar to others. Plus knowing patterns. 1,4,2,5 etc. helps. Do I know all my notes on the neck ? No, I know some, give me 5 seconds I can find every G in the neck. By using tab, patterns, and knowing some notes.
When the guitar players capo 3 frets up playing G fingering?? A# ?? No worries, I move my ‘pattern’ 3 frets up.
