Adding an effects loop and expression pedal to an EHX Freeze

[Lameller]

Bump - if anyone could do a simple write up of just the FX loop mod I would be grateful!

I am also just looking to do the effects loop mod without the expression, but am also a newbie and a little clueless. Also without the expression jack, couldnt it be wired for a send and return jack? That is what I would like because With the current drawing it is basically separating the dry and wet so it would need to go into a stereo pedal to recombine right?

Can't be done, at least with what any of us knows now. After posting the mod diagram above, I realized that there was still a dry signal present when it was turned all the way down and I couldn't get rid of it. Some sort of weird phase issue I think. I gave up and just bought a Superego which does the trick wonderfully.
