Why did Fender Duo-sonic, Musicmaster and Mustang pickups have covers made without holes in the covers?
The flatwork used in these pickups are the same as used in the Stratocaster. If you’ve ever taken the covers of the pickups, you will see that all the rod magnet pole pieces are flush with the top of the bobbin. The magnets used in the pickups had a length of .625″ and the diameter in the earlier pickups were .197″ and later was .187″. The magnets in the flatwork slightly extended out the bottom on the older Duo-Sonic and Musicmaster pickups. Because the magnets didn’t extend through the top of the bobbin like Stratocasters, there was no need to have holes in the cover.
