I can upgrade the pickups and electronics in my RSD ME and still not be at the price of a German ML, so they (smartly) are making sure there are other differences to justify the prices. At the same time, if your budget has you looking at a RSD ME then you're looking at a really solid choice, which is great.
Exactly!
IIRC, the pickups in the RSD ME are single coils, the same as the ones in the Will Lee, so the Hum cancelling pickups are not necessarily an upgrade, more a preference, albeit more expensive.
