Re: Dimarzio vs Duncan - What compares?
As a few guys have already mentioned, there's a major difference in Dimarzio's and Duncan's humbucker pickups.
I've tried a heap of pickups from both camps and it must be an unspoken rule (or maybe agreed upon in a darken alley) that they voice there pup range differently. The cynic in me suggests it's to stop smaller manufactures grabbing a bigger slice of a relatively small replacement/OEM pickup market.
To use an automotive analogy, it's a similar situation to GM and Ford. I've never seen a vehicle from either company that's the same. And of course, both sides have their rabidly loyal followers

. Duncan & Dimarzio both have a stable of top shelf artists flogging their products, further dividing their individual markets and keeping the rest of the competition light years behind.
I'm guilty of slagging Dimarzio pup's in the past (I blame the Tonezone since it was my first replacement pup

), Luckily, I tried a few more.
The best Dimarzio's I've used, in order are:
1. Breed neck in the bridge
2. Paf Pro (neck & bridge)
3. Breed bridge (in the bridge

)
To all you Dimarzio haters, check out Steve Vai's tone on Eat em' and smile. It's a Paf Pro through a heap of different stock and modded Marshall's (approx 12 in total and not a single Carvin in sight). He also used various distortion pedals. I don't know how many times I've heard that Vai used a ton of effects on Eat em' and smile. The reality is he used some reverb and a Harmonizer on a few tracks. His effects fetish probably started when he earned a few dollars and he was all geared up for Skyscraper.
Anyway, despite my Dimarzio praise, the JB is my favourite at the moment
