Degaussing ?
« on: June 02, 2010, 09:16:32 PM »
On one of my guitars that I had earmarked as a possible candidate for some BKPs, and after reading several favourable reviews, I fitted (BKP purists look away now) a set of Seymour Duncan P-Rails. I was intrigued by the idea of single coil, P90 and humbucker all in one pickup and although they don't quite cut it as full on examples of any of these pups as BKP users know them, they do provide some interesting and very usable tones.
While I was looking through the Seymour Duncan forums for other users experiences with them I came across a thread about how the tones from these pups can be "improved" by degaussing them, and indeed this is an option offered by Seymour Duncans custom shop.
I have a proper degaussing tool from my days of working with multi-channel tape machines and used it to degauss the tape heads, and may yet try it.
BUT.....to me this sounds counter-intuative - the reason for degaussing is to remove unwanted magnetic fields - something you don't want on tape heads, but to remove the magnetic field of a pickup to improve tone seems totally wrong ?
If it's such a great way to improve a pickup then surely Tim would do it as standard practice ?
Any of the technically knowledgable among you have a definitive view on this ?   Cheers

I know Lollar do this, I think it is to simulate an aged magnet.  Take a really good Gibson PAF from 1959, it may be AV for example but it also might sound good due to 50 years of ageing so a new magnet is degaused to simulate the age factor.

So it depends on whether you want the pickup to sound like it would in 1959 or how it does today.

How a degaused A5 magnet compares to a none degaused AIV magnet I have no idea but it could be  a different route to a similar sonic aim.

Could be, I have no idea :?
