Jaguar pickups: 1963 vs. 1964
To stag or not to stag?
1963, the polepieces are “flat”:
… in 1964, the polepieces were changed to “staggered”:
Note: In both pictures the “sawteeth” claws of the pickups face the wrong way – factory mounted. :-)
By design, the two short “teeth” were meant to sit under the treble strings (at the time of the design wound g-strings were common*, hence the four longer teeth, each for a wound string). It would be interesting to hear the differences this makes (if any). I can only guess that the magnetic field is slightly changed, so it should be wider were the “teeth” are shorter, which probably will allow for a less trebly sound. To guess even more, I venture this was meant to even out the tonal difference of wound and plain strings.
