Can you identify this pickup?

[Fardeen]

Hi, I recently bought an used Ibanez S470 in which the stock neck pickup had been replaced. The guy I got it off couldn't remember the brand of the pup. So I was wondering if you guys could help me out on this. Here's a picture (it's the humbucker):-

lol... I know its hard to identify a pickup on looks alone as all pickups look pretty much the same, so I'll post some of its characteristics as well. For starters, it has a much higher output than the bridge Ibanez AH2 pup. On clean, if I turn up the bass, it has a sort of slight natural overdrive. On distortion, it sounds really heavy and crisp. And the noise level on distortion is minimal. And its quite bassy on both settings. As far as it being active or passive goes, I have no idea on the issue, so would someone care to enlighten me? Hopefully, all this info will be enough for you guys to have a crack at identifying it.

Btw, my guitar instructor thinks its a DiMarzio but I can't be sure since its logo has rubbed off.
