I swapped out pickups in my cheap Squier P bass yesterday. Dropped in a 1985 Dimarzio pickup. I can't believe how much louder this pickup is against the stock Squier pickup. I had to pad my GK, it was clipping like mad with the input volume at 9 o'clock. The old Squier pickup wasn't weak, it would hit the peak light every once in a while too, but the Dimarzio is a beast! It's not all heat though, it has plenty of warmth and just sounds like a great P bass. Do the new Dimarzio P's sound this good?
DiMarzio Makes some great stuff. I can't speak for every pickup they make, but I really like my Ultra Jazz pickups. Glad you got your wiring issue sorted out.
I have Dimarzio pickups in my Nash P bass and they sound great..I also believe they make pickups for Sadowsky...
