My left hand 'knows' the open string node positions at the nut end inside out, but I've have never really taken much notice of them at the bridge end other than the occasional 'pinched falsies' - thumb on node and pluck behind with 1st finger. The last time I looked at bridge-end nodes in any depth was over 30 years ago - I was playing a Jazz bass which has a lot more 'geography' going on. So it's baby steps to some extent. The first step has been adding an unobtrusive visual aid - a strip of transparent tape marked with a Sharpie for the 4th, 5th, 6th and 7th node positions measured from the saddle. At least I can confidently learn the positions without having to re-locate them every time:

Next stop - the harmonic 'scale':

Other higher nodes are available on the fat strings but seem pretty tricky to sound with this method - maybe later!
