MM's preamp in his original bass is a Bartolini that was installed by Roger Sadowsky. There is a lot of debate on whether it is a Sadowsky preamp or something else...

There is an interview by J. Ross on YouTube where MM says that the preamp in the Fender signature models is designed by John Suhr.
the preamps for 4-string and 5-string are different. The 4-string has a Fender FMEQ in a molded box:

The 5-string has an open circuit board that looks much more like my old Pensa-Suhr preamp.
