Beautiful Jazzmaster sounds, now with active pickups and NO HUM !
These pickups are able to keep the original sound and are great !
If in doubt, check Puisheen or Kris Barocsi's videos on YT.
Also, I confirm that you can connect any solderless EMG pickups (I put an EMG 81 in the bridge on my Jazzmaster)
The installation is as easy as can be.
I have yet to figure out the settings that the 2nd circuit offers, but in any case I am very happy with what definitely feels like an upgrade.
