Am i missing something. I havent read the whole thread properly so do correct me.
My definition of choking a note, is because the string at some point along the neck is too close to the frets. Of course there is a buzz you get, but depending on the relief of the neck and also the trueness and levelling of the frets, one will get a few choked notes.
A super low action will go past the buzzing point and choke a note/s.?
A higher action will let the strings vibrate.?
I really dont think pickup height has anything to do with it.
