Squier Classc Vibe '60s Mustang

So it looks like Precision split pickup halves have opposite windings and opposite magnet polarity. connecting them in series allows hum cancellation with all four strings in phase. The traditional Mustang pickup halves are all wound the same direction, with all magnets the same polarity. Connecting them in series “tail-to-tail” Effectively cancels hum, but with opposite signal phase between the halves.

I suppose Fender was saving money building all of the Mustang pickup coils the same, for what was conceived as a “budget” or “student” bass.

I’ve never heard or read of anyone bothered by the difference in phase between the E-A and D-G strings on the Mustang.

The new American Performer Mustang obviously required a redesigned split “Mustang” pickup to allow combining with the Jazz bridge pickup.

Fascinating.

Just a data point...Your post made me curious about the pickups in my MIJ Mustang RI so I checked them and the magnetic polarity of the two halves are not the same, they are opposing.

Interesting! Do you have a way to check (oscilloscope) if the pickup signals are in phase on all four strings? Makes sense that the Japanese designers would pay attention to a detail like that...

All four magnets in the “Duncan Custom Shop” labeled set on my JMJ are all south polarity, and the waveforms/transients are definitely opposite phase. But the JMJ’s pickups were designed to exactly duplicate the pickups in a 1966 vintage Mustang.

As I said previously, the pickups in my old 1974 Mustang were also all-south and out of phase.

Now I wonder about the polarity of the pickups in the new Classic Vibe Mustang, the CIJ Mustangs, and the old “Duncan Designed” Squiers...
