Magnet Wires differences among suppliers

[SonnyW]

BTW I was thinking about buying an Extech, but is there any software(/hardware) for PC able to measure all the parameters such as Inductance, capacitance, Q, resonant peak etc...?

In my experience most LCR meters won't give you as accurate a measurement as the Extech, due to the pickup being a low Q device. I made the mistake originally of buying a different lower cost LCR meter and it was off by a factor of 2 or more in some cases. I knew this meter would be off some, and I ordered the Extech, and when it came in I was really surprised. I still use the other meter to verify tone capacitor values etc. but not for inductance on pickups.

Here is a thread where I embarrased myself by posting values that were way off, then when the Extech came in I redid the measurements and wow was I off the first time. So I posted the corrections, and then Joe Gwinn jumped in and was a big help so I'd suggest reading this thread before picking an LCR meter.

Well, following T's suggestion I've tested the DCR of the wire, I cut 3mt off each spool, the dcr was 17,4ohm for the elektrisola wire and 17,7 for the mojo wire... Is that much? I believe that 0,1ohm per meter might lead to a final difference of 0,1k between two "identical" pickups.
Do you think that such a difference might turn out into an audible difference?

I would think the wires are real close. very similar.
Why not wind another coil.
Maybe there was a stretched place, a thin place where you soldered.
I would give the wire another chance, I really like Elektrisola wire, and all I have used is high quality.
So try not to overheat the wire when you solder the eyelets. You want enough, quick heat when you solder it.
when the wire is wrapped around the eyelet, Then lightly scuff the wire with fine sandpaper.
Another wire to consider is the Elektrisola 42 HPN.
I have both HPN and HFV, and prefer the HPN for Single coils.
I save the HFV and PE for vintage rewinds.
Good Luck,

This is just a wild guess, but based on your description of how they sound, I am wondering if you checked the phasing. If you get a weak thin hollow sound when two pickups are used together that can be due to the pickups being wired out of phase. A quick way to check is to reverse the hot and ground leads on one. But if the thin weak sound is all the time, even with only one pickup selected it isn't phasing. Another difference might be just due to stretching like T said or winding pattern, or soldering, but I wouldn't think 0.1K of DCR is going to make a huge difference in tone all else being equal. If I remember, you said you thought the DCR's were very close. Anyway it is just a thought.

Sonny, I've checked polarity and wind direction, the PU wer not installed out of phase.

in the meanwhile I built a new set, with the same specs and Elektrisola wire: everything seems to be just fine, unfortunatelly I don't have here with me the other set, but I believe that something went wrong with the "testing environment"...maybe....
