By reading other threads seems like the "X" series goes both deeper and higher than standard EMG. I have one bass loaded with an EMG P/J set(and a spector tonepump pre) and another one with a P/J X set (and a EMG BQC pre) and to me seem like the X just goes deeper. In one of the other EMG X thread, someone suggested to check the "resonant peak" in the PDF on the EMG page. The "resonant peak" value on the X pickups is always lower or on par with the traditional one, while “Thump” is always increased. But since I know absolutely nothing about it (and about electronics in general)... Do someone knows what does it means (in a “for dummies” way)? I'm trying to understand because I'm thinking of swapping a pair of 40TW for a set of 40DC or DCX (to use with a tonepump). I'm used to bright sounding pups, and while the TW are good and versatile, they are quite dark. I'm looking for something aggressive, grindy and good to cut through a busy mix, hence the DC/DCX choice but it seems ther's no abundance of DCX audio clip, let alone a comparison against old DC... Thanks in advance.
