Hello!
I finally got around to wiring up a Multiplex I've had populated for a while and ran into some problems.
I'm trying to build one very similar to this one here:

Mine looks like this so far:

What is happening:
-Bypassed, my guitar signal comes through clean
-When I plug power in the modulation LED lights up solid and stays that way. Changing from delay 1, off, or delay 2 does not have any effect.
-When engaged, the power LED comes on.
-At no point to I hear any guitar signal when engaged.
-Engaged I get a very loud constant BZZZZZZ noise, even with the amp volume turned all the way down. This noise can go away if I tilt the enclosure around to various positions. It seems like if I have the enclosure flat, no noise. Once I turn it on its side or flip it over - noise. The noise also seems to be slightly different on its side, and then loudest flipped.
-I held down the "detune" for about 20-30 seconds with no LED light coming on. I haven't calibrated this yet, and the trim is turned fully CCW.
Some errors I made:
-I have the in jack wired to the out on the 3pdt pcb, and the out to the in on the 3pdt pcb.
-I wired the modulation daughterboard ground and power directly to the dc jack. I probably should have wired them to the 3pdt pcb
I'm guessing something somewhere is touching something it shouldn't be when titled, or perhaps there is a bad connection. I'm pretty confident in my multiplex component soldering, I'm guessing the issue is somewhere in the daughterboard or the other connections to the jacks and so on.
Any suggestions would be most welcome.
Thanks!
