Having upgraded a bass with an EMG PJ-X set, I wanted to try something passive with my next project and having read good things about DiMarzio, I gave them a try as they were at a great price. One of my stipulations was for a noise-free single-coil and knowing that the DiMarzio J pickup is actually two coils side by side wired in hum-cancelling configuration, these fitted the bill. These had a considerably hotter output than the original pickups on the bass, with more pronounced low mids and of course, the J was silent when soloed. Another great feature of the DiMarzios is that you can adjust the pickup pole heights with a hex-wrench, allowing you to set a consistent output across a bass with more a pronounced neck radius. As the pickups are 4-conductor wires, you also have the option of wiring them in series or parallel, giving further tonal options. Easy to fit, they look great and sound even better, I'd happily recommend these pickups looking to breath a bit of life into a bass.
