Beveled magnets?

I installed an AV '62 RI bridge pickup on my Partscaster '62. What a great sounding pup! I'm just wondering why the magnets are beveled? I don't remember seeing beveled magnets on an early 60's Tele pups or any Tele pickup before and after. My '69 has flush ones.

edit: never mind, haven't got a clue. Interesting question anyways. :)

the MIM 60s has beveled magnets, doesn't it?

I always thought they were introduced because people started using lighter strings with no wound G. But I have absolutely no idea about the real reasons behind it.

Hi Weelie! I don't mean staggered magnets, like on MIM 60s. I mean that the top of the magnets on AV '62 RI are not flat, the edges are beveled.

BTW, here's a sound clip:

Yeah, sorry about the big file. It was captured with my Sony digital camera which makes large files only...

Well, it sounds and looks good anyhow. :)

Yeah, I think I've seen those beveled magnets on after market pups only. Maybe it just looks more boutique that way, and doesn't wear (look wise) as easily? Hey, maybe they though somebody might cut their hand on the edges. :P

When I got some Tele pickups wound by OC Duff two years ago, he offered the option to bevel the polls. From what I recall there is an argument that it will somehow focus the magnet-to-string a bit more but is probabaly mostly a cosmetic thing.

Quote from his webiste:
"Bevelled magnets, or non-bevelled?"
I doubt if I was blind folded that I could ever hear a difference between the two. Bevelling may have an effect on how directional a magnet is upon the string, but that's about it. I bevel and polish my magnets upon request mostly for aesthetic reasons. Fender used to bevel their magnets so they'd slide into the bobbins better and also to grind off any chips in the magnets. Those old Fender pickups sure are chipped up though.

I did not have mine bevelled.

I don't believe that beveling the edges of a small diameter magnetic rod is going to focus the magnetic field, at least not in any sense that is at all a practical method for improving a pickup. The more likely reason is the story I've heard that beveling was simply a practical way of removing burrs and sharp edges that were left when the pole pieces were cut from a longer rod of metal.

I had the same question. My 60's relic strat has the same even beveling on all the poll pieces. My understanding is that that is not accurate to 60's specs, but that it doesn't affect the tone either.
