This only happens when my Zon Sonus is plugged in, with other basses the problem does not occur.

When kicking in my Korg Pitchblack tuner or any EHX pedal there's a loud pop, the volume from my Zon is completely gone and then slowly returns. Obviously there's something wrong with the Zon as my other basses (an active Jazz and a Ric) do not suffer from this problem.

Now when I hook up my EBS TremoLo in front of the tuner in my signal path, the problem also does not occur with the Zon. While this does fix the problem, it means I can't ever use the Zon without the TremoLo in my signal path...

What's going on here, is the 9v battery in my Zon being short circuited by engaging these other pedals or something? The Zon has an old Bartolini 2band preamp.
 
I got nothing.
It has to do with the preamp of your bass turning off then back on when you engage the tuner but I don't see what could cause this.
As long as you use a mono jack, not a TRS the pedal you plug after should be irrelevant and play no role.
