Mhhh, ok, so more like a traditional mini humbucker construction (as opposed to a firebird where the magnets act also as polepieces) albeit with narrower and spaced coils, but then without the adjustable pole pieces on both coils of the filtertron?
I really like these but I understand MM has no plan to release them as aftermarket parts and I cannot afford a second St Vincent, especially with the crazy prices here in Europe. :-/
