Maybe the Pappalardi mod? I have a Felix pre-owned fifties EB-1 (not his No 1, that gathers French Fries grease in Toronto's Hard Rock Café), refinned cherry while he was still alive, and it has a notched tone pot (I heard he did that on all his EBs) which starting from the middle position attempts to change the original singlecoil sound to humbucker mud mania. Not quite there, but it tries hard.
