Never heard about a particular way he tuned his B. What does he do, specifically?
I don't think anything specifically w/ the B- string !
But Ed was notorious for just picking up his guitar ..., tuning to himself ..., telling Mike Anthony to tune to his guitar and then proceeding to record wherever they happened to be tuned at the time ....
Mostly that is in the vicinity of Eb, mainly because of Dave's voice ....
But other than that, I don't think he tuned in any special manor ?
