Reversed polarity is Easy. Just flip the magnetBB pro: unbalanced coils, degaussed rough cast A5. Many people like them and so do I.
BB pros come in pairs, one with reversed polarity. So the original PCB switching functionality can't be utilized with a regular pair of PUs.
People will use it as an argument to get a discount. You'll have to be prepared to wait for the right customer or restore the guitar with a new set of BB pros.
