I received an EHX Small Clone recently, and had it open to do some tweakage. I put the thing back together and it doesn't work

I opened it back up and 3 wires had broken at the solder joint.
I stick them back in, easy enough. Today, I notice the depth switch is no longer working. I open it up, and of course, another wire had snapped at the joint. I heat up the iron, put it back in, and as I'm putting it back together, the ground wire from the battery clip pops off the output jack.
After fixing the wire and putting it back together, I must ask. Does EHX just use cheap wire or what?

I wasn't roughing the board around while it was apart, no more pull on the wires than that which might commonly happen when moving stuff around. It just seems far too brittle.
