Spending this morning writing down all sorts of notes for me to keep by my amp so I can keep them in mind during my practises, and also annotating my physical tabs so I can visualise the picking patterns. This ended up really helping, as I've realised I might be picking No Ready to Die slightly off in the second half.
From the start of that half, it's one note downwards and them a sweep up for the next 3 notes, then down, and then up 3, down one, up for the vibrato. In other words, it's exactly mirrored, but I don't think I was playing it that way yesterday. Gonna focus on getting that right, as well as making my sweeps more like a raking motion rather than a picking motion today! Already think I've got somewhere, so perhaps a video tonight?
