I'm not referring to the sound, but rather, is there some kind of test which can tell the one metal from the other?<br /> Thanks.

Mr. G, I've been following you PU threads. I don't believe it is possible once the PU has been assembled. It may not be possible beforehand unless you know what you ordered from the magnet guy.<br /> <br /> Stewart McDonald makes a real nice sounding Tele PU set and they sell their PUs separately. I have a couple sets of these in guitars and have used them for customer builds with no complaints.

It won't tell you for sure, but you can make an educated guess by seeing how much magnetic pull there is. Alnico 5 charges much more than Alnico 3, so if you (or someone else) have/has a good feel for how much pull a magnet has on a tool (I use my 6" ruler) then it might tell you something. If it bites really hard it probably is 5, if not, it very well could be 3.<br /> <br /> The two materials will have color/texture differences, but probably only noticeable to the one who bought the magnets originally at Fender, since those properties can change depending on sourcing as well.

Thanks.<br /> I was hoping that there might be a magneto-meter of some such thing to measure the pull, but yes, perhaps I can test the pull of various pickups I have laying around and see if a difference can be noted.<br />

"I was hoping that there might be a magneto-meter of some such thing to measure the pull, "<br /> <br /> There is such a thing - the most devoted pickup builders own a gauss meter and could certainly measure it. If you know someone who owns one then go for it, but it would be too expensive to make sense in this case.

Consider simply asking the company that made your pickups.

That's Fender. They're a bit vague on what "Tele Original Vintage" was in 2002 - not that I blame them.<br /> <br /> <br /> ... but in any case, I have found someone an hour's drive away to do a rewind. Alnico, Shmalnico, it's getting 8,000 wraps.

Probably a3 at that time. More than likely.

I just found a thread which confirms my own memory of the time: that somewhere around 2000, Fender changed the Original Vintage Tele pickups from Alnico 5 to Alnico 3.

Consider this: <br /> <br /> I you took 2 pups that were identical in every way except that one was A3 and the other was A5 and swapped back on forth on the same guitar, could you really hear the difference? I seriously doubt that I could.<br /> <br /> It is fun to tinker around though.

If there was just Alnico 2.8, would that suffice?

I found a copy of the Fender Frontline catalog on my bookshelf this morning that is Volume 26, July-December 1999. On page 157, it lists "Original Vintage Tele" pickups. About halfway through the product description it states, "Lovingly recreated using Alnico 3 magnets, enamel coated magnet wire, fiber bobbin, and cloth wire for definitive Tele 'twang'."

Obvious: Alnico 5 is 2 more.

"Yes, but these go to Alnico 11."

It says...<br /> <br /> Bridge: 7.2K; inductance, 3.27 Henries<br /> <br /> Neck: 7.7K; inductance, 2.45 Henries<br /> <br /> And, yes...for whatever reason, the neck is listed as "hotter" than the bridge.

I emailed him and asked for 7.6. I hope it's not finished before he gets the email.
