Undulator Tremolo troubles

This Xvive tremolo pedal was relegated to being a paperweight because of an intermittent signal problem.

Instead of getting it fixed at the pro-shop, my friend gave it to me. Well, what good is it to me if it doesn't work?
So...

I've tasked myself with fixing it.

JOB 1
Pull it all apart.

Easier said than done.

The PCBs are thin and super-flexy. If there wasn't a crack in a solder-joint there are sure to be dozens now after trying to separate the main board from the jacks-daughterboard.

The gap between the pin-header and the board grew as I tried to pry the boards apart, NOT the anticipated female/male pin-headers.
Is this thing crazy-glued together? Trying to pry it apart, I realised maybe the header-pins have no female counterpart, and I'm trying to take apart something that needs heat and a solder-sucker.

Note how the gap between pin-header plastic and PCB has widened, while the "Crack" between the "male/female" pin-headers has not?

Any Xvive-xperienced people out there. Have any of you ever been Xvive-xperienced?

I don't want to make this a scavenger parts-pedal (though free vactrols are tempting));
supposedly the only thing wrong is the intermittent jack problem.


Looks like I've got to desolder. *sigh*



Advice?

That's above my paygrade.

If someone handed that to me and said have at it, no schematic, I would take the boards apart. Two double sided smd boards? Turn it into a project to work on between projects! Trace out a rough schematic, figure out the circuit blocks, try to get it running.

But that's just me, I love puzzles. YMMV

If you can't get it fixed send the separated boards to the pro shop.

I'm sure there are ppl here more knowledgeable than I that could chime in.
