On my new bass I'm thinking about an MM in the MM sweet spot with a soapbar at the neck position. I'm thinking Kent Armstrongs too, if that matters. I'm wondering what people think of this. I'm concerned about how the pickups would be paired for eachother, as in unequal output. Also, could I have a series/parallel switch for each pickup? And how would this sound different from a double soapbar configuration?
