Ok, I've been messing about with the just-a-nut 2 and the bridge on my thumb. I raised the action because I was getting this 'click', but it didn't want to go away. I also noticed that it'd developed a buzz at the biridge when played acoustically. I got my manual, and read about the set up they do in the factory. I returned everything to that and the acoustic buzzing stopped(the only reason I can think of is that because the strings have formed grooves in the saddles where they've rubbed, when i heightened it, it made them buzz because they weren't a snug fit in the grooves they'd formed, if that makes sense...btw, the grooves are from the round wounds digging into the metal). Anyhow, I still got the click. It's due to the strings touching the frets, but it will not go away. I've got plenty of relief too. Now, is there some secret to getting rid of this? I've tried rolling back the treble and presence on my sansamp, but I lose all clarity, and also a lot of the warwick's tone.
