G&L tech resources: Pickups


This is the wide-bobbin version of the Magnetic Field Design (MFD) pickup and at the root of my love for G&L instruments. And hence this website! First used in 1983 on the SC-1 and SC-2 ‘entry level’ models, it went on to be integrated in the Broadcaster, later renamed to ASAT and nowadays the ASAT Special. And between 2008 and 2017 on the SC-2 (reissue) of course. A Jumbo MFD neck pickup is placed perpendicular to the string direction and its cover measures 3.600”x1.100”x0.660” (LxWxH with an uncertainty of ±0.015” in all dimensions). The distance center-to-center for the outer pole pieces is 1.970”±0.015”. However, the bridge pickup is slanted by (about) 15° which is reflected in its cover measuring 3.775”x1.100x0.660” (with an uncertainty of ±0.015” in all dimensions) with a 2.150”±0.015” center-to-center distance for the outer pole pieces. Note this angle is similar to the bridge pickup on a Telecaster and/or ASAT Classic. Two ASAT models even have 3 of these MFD pickups: the ASAT S-3 and the ASAT Trinity Special Edition, the latter with the middle pickup Reverse Wound/Reverse Polarity. The pickups on the 20th Anniversary model allegedly have 180-200 extra windings. Since the bobbing aperture was not modified, one should be very careful if the cover needs to be taken off on this model. This problem in producing a hotter pup was solved on the ASAT ‘Super’ by using 42 AWG wire for the neck pickup and 43 AWG wire on the bridge pickup. The name for this section is how it is referred to on G&L’s website, store, and instrument specifications. So no, it is not “G&L P-90” or something like that, as one frequently encounters. The MFD and P-90 are fundamentally different in construction and sound. The G&L version of the P-90 has its own chapter.
