The Fender Pure Vintage '59 set is three of the same pickup, with AlNiCo 5 poles and formvar insulated wire.


Fender Pure Vintage 59 Bridge
DC Resistance: 5.94K
Inductance: 2.173H
Calculated C: 107pF (117-10)
Coil width: 0.5315"

Resonant Peak:         dV: 14.6dB f: 10.0 kHZ (black)
Loaded (200k & 470pF): dV: 7.0dB f: 4.27kHz (red)


Fender Pure Vintage 59 Middle
DC Resistance: 6.02K
Inductance: 2.156H
Calculated C: 124pF (134-10)
Coil width: 0.5185"

Resonant Peak:         dV: 14.8dB f: 9.37kHz (green)
Loaded (200k & 470pF): dV: 7.0dB f: 4.27kHz (gray)


Fender Pure Vintage 59 Neck
DC Resistance: 5.99K
Inductance: 2.194H
Calculated C: 131pF (141-10)
Coil width: 0.5390"

Resonant Peak:         dV: 14.6dB f: 9.06kHz (pink)
Loaded (200k & 470pF): dV: 6.9dB f: 4.22kHz (black)

Pole piece gauss strength: 900G - 1050G, AlNiCo 5



Bode plot:





Another oddity related to the pole pieces is that I only read around 900 Gauss for some of the taller poles that typically read ~1050. Definitely too strong to be AlNiCo 2,3 or 4, in any case.

I bought a second set of Fender Pure Vintage '59's for a new guitar project. I measured this set in order to compare it against the first:

Fender Pure Vintage 59 Strat #1
- DC Resistance: 6.164K ohms
- Measured L: 2.273H
- Calculated C: 93pF (103 - 10)
- Gauss: 950G (AlNiCo 5)

Fender Pure Vintage 59 Strat #2
- DC Resistance: 6.170K ohms
- Measured L: 2.240H
- Calculated C: 95pF (105 - 10)
- Gauss: 1000G (AlNiCo 5)

Fender Pure Vintage 59 Strat #3
- DC Resistance: 6.019K ohms
- Measured L: 2.260H
- Calculated C: 94pF (104 - 10)
- Gauss: 950G (AlNiCo 5)

#1 unloaded: dV: 14.8dB f: 10.4 kHz (black)
#1 loaded (200k & 470pF): dV: 7.0dB f: 4.27kHz (blue)
#2 unloaded: dV: 14.8dB f: 10.4 kHz (red)
#2 loaded (200k & 470pF): dV: 7.0dB f: 4.27kHz (blue)
#3 unloaded: dV: 14.8dB f: 10.4 kHz (pink)
#3 loaded (200k & 470pF): dV: 7.0dB f: 4.27kHz (blue)




Even though I bought the first set almost four years ago, this most recent set has near identical values, though where as the first set showed some variance in the capacitance, this newer set has freakishly identical values. Similar to the first set, I also get a slightly below average reading of flux density at the tops of the AlNiCo 5 pole pieces, out of the box.
