WHAT IS THE TONE OF THE NORDSTRAND AUDIO MM4.4 MUSICMAN® BASS PICKUP?

We hear a traditional tone but with a bit more mids and body. Top end is extended, nice and crisp, and a sweet fullness in the lows. Series and parallel are fairly similar with a bit more mids in the series winding.
Note #1: The pickup used for this video is the MM4.2, a 4 string pickup. The 5 string size/shape will sound similar, but not exact as they will use a longer magnet. Nordstrand is engineering them to sound as close to each other as possible.
Note #2: This pickup was recorded in both parallel and series wirings. This is something that be done with majority of Music Man style bass pickups. A player can choose to hardwire the pickup in parallel or series, or can have a switch to access both. Most commonly, the MM style of pickup is wired in parallel.
