I've got a random split P pickup with 1/4" pole pieces, but it doesn't resemble a Seymour Duncan Quarter Pounder in any other way. The leads are different colors, and the covers are slightly larger. I don't remember where I got these, but they sound pretty darn amazing. Just the right amount of punky zing on top, plenty of fundamental mass on the bottom. So, amazing Talkbass collective, what do you think these pickups may be?
