I was able to get the Pick ups in my Schecter Model T ( Robert DeLeo ) bass switch out it had those duncan design pick ups pure crap and put the Bill Lawrence in what a diffrence. Very thumpy good tight sound the P reminds me of a vintage P pick up. The J is a littel hi fi. The pick ups are hum cancelling but when i turned the tone up they still made some noise, i wonder if this is common. I will right back after i give them a better work out. The thing i dont get is that Schecter made a great bass but they put such bad pick ups in.
