Congrats on your pickups!
Since your nickname is JPwannabe, I guess your into petrucci's sound.
I have a JP
bridge humbucker, and it's quite different from steve's special, though it's character is the same. It has more punch in the lows (which really rocks!) and mids, but slightly reduced highs, though very notififying (imo it's flipside).
i had the pickup in my RG2020 which has a
mahogany body, and the highs became too dark for that guitar, so I put it in a basswood RG model, where it sounds great.
So my dream pickup will be the steve's special, with the JP custom lows
Another thing is that they have too big holes for screws if you want to mount them on a pickguard or mounting rings. You'll have to improvise something then, but it shouldn't be too difficult. There's no problem for direct mounting.
BTW i payed about $75-$80 (can't remember the actual price) for the pickup, a year and a half ago, on ebay.
The seller didn't note that it was dimarzio's so I guess the traffic wasn't that big because of that.
Anyway, good luck with your pickups.
I guess you'll get almost the same price for them if you don't like them and decide to sell.
