The MM4.4 is for the player who wants the advantage of all the switching options available with spit-able pickups, only without single coil noise. Each row of magnets is divided into two coils, so the pickup can be split and remain hum-canceling in any configuration. Front coil, rear coil, series, or parallel, this pickup has all the basses covered. Wired in parallel, you can expect classic MusicMan tone—scoop, power, and zing! While with series the midrange is given an extra hand in facilitating scoopy scandalousness. With a tone that is similar to that of the MM4.2—powerful low end, classic scoop, and pleasant high end—combined with the MM4.4’s coil switching agility, this pickup provides 70s style tone with a slightly darker, more modern twist.

History: The MM4.4 was born when some the technicians at Nordstrand accidentally burned a hole in the sonic continuum (we’re not sure what that is either) with the high-powered industrial laser we use to cut vulcanized fiber. Someone decided to throw an old MM4.2 through the void to see what would happen and, low and behold, the pickup was instantly spat back in four parts—four separate coils. Since that fateful day when the hand of an inter-dimensional entity gave us a clue as to the trajectory of the MusicMan design, we have been working on finding ways to implement this quad coil conception into other pickup models. This pickup was immaculately fabricated in Redlands, CA.
