I just took the original Jackson pickups out of my bass, and installed a EMG P/J set with the BTC system. There is a major difference! I can't believe the difference in tone from the Jacksons and the EMG's. these new pickups sure made this Jackson come to life. I would recommend these for sure. I'm playing a Jackson Concert EX,into a Sans Amp Bass Driver,into a Peavey Firebass 700 head,then into a 4x12 Peavey cabinet. This setup now sounds great!
