We started with 2 of our hugely popular 9J passive hum-cancelling Jazz bass pickups and installed them in a soapbar shell. With soapbar mounting instead of mounting ears in a nice squared shape, we created the 2J Squared Quad coil pickup. We made the J pickups work together as a dual humbucker or as a J-bass when coil-split. When wired as a series humbucker, they are big and growly with high output. When wired as a parallel humbucker, they are fat and round but with focus – like when you have both volumes on full on a J-Bass. When wired to coil cut, they are precise and clear. And they are hum-free in all setups which can be easily chosen when you install a toggle switch. They can be used without a switch, but you get a lot more flexibility if you have one.
Because 2J Squared are have blades instead of poles, they work with a range of string spacings. They are internally shielded and are wired with shielded cables. These pro-level pickups are fully hum-killing even on the noisiest stage or studio. They are sweat-proof and won’t make horrible noises when you hit them with the strings.
We make them special for neck (Bass, -B) and bridge (Treble, -T) positions so they balance well when blended together or played separately.
