I measured resistance and got:
Single coil
std kit: 5.4k
Sample: 5.8k
Humbucker:
Std kit: 8.8k
Sample: 6.8k
The single coil is what I was expecting, but the humbuckers surprised me as it seems that the sample one may actually have less coils... unless it's thinner and better wire...
I don't have any ways of measuring inductance so my test doesn't really mean much I guess...
