Re: Duncan '59s vs Gibson 490s
Well, the 490R is made with Poly wire, mine measuring 7.68K, with an A2 magnet. This particular recipe sounds like mud to me, no matter what guitar, even though it gets worse with LPs and semi-hollows.
Changing the magnet with an A5 will clear up the upper frequencies making it usable, but a bit bass heavy. The best overall recipe is putting a ceramic magnet, making it like the 496R, but I personally don't like the inherent harshness in the sound that particular magnet produces, so I've ended up using an A4 magnet, which made it ok, very usable but with no personality.
The '59n is made with Plain Enamel wire, mine measuring 7.18K with an A5 magnet. This recipe is (to me) the closest to perfection for a neck p'up.
The inherent bass-heavyness of the A5 magnet is counterbalanced perfectly with the tight wind and the lower count of turns. In my case, due to the lack of mids in my rig, I've tried putting an A4 magnet and bingo! I've found the perfect recipe for a neck p'up.
Afterwards I've found that this recipe worked just as well in other people's guitars AND rigs as well, so it became a standard to me.
Considering that the Gibson p'up costs over a 30% more than the Duncan, for me choosing one over the other is a dead-on-no-brainer. :naughty:
HTH,
