Spec-wise (resistance), the Oildale and Fender Nocaster bridge pickups are very close. And both use A3 mags. You may not hear much, if any difference, between them. The Bakersfield has A5 mags, fewer turns, and a little lower resistance. The Bakersfield should sound a little bit sharper/brighter and sparkly in tone. If you play with a good bit of over-drive or distortion, you may not hear any difference between the three. That said, the Fender Nocaster is machine fed during winding (extremely consistent). The Cavaliers are human hand-fed during winding (scatter-wound, somewhat uneven). When playing clean, those who pay close attention to tone seem to notice the difference in tone with the scatter-wound. I think the scatter-wound pickups sound a little richer/more complex in tones/over-tones. You're not so likely to hear this, though, if you play with very much over-drive.
