I've completed a build of the Phase Royal and the 8-stage JFET module. However, with everything plugged in, I'm not getting any wet signal through the pedal, i.e. with the "mix" knob turned all the way up, I get nothing, and when turned all the way down, I get a clean, dry signal. The LED lights up and responds to changes in the "rate" knob, and the input/output pots seem to be working as well, since there's an audible boost to the signal when I turn those. The mix knob seems to be the only problem.

I've checked my solder points and they look good to me, although someone may be able to spot something I've overlooked. It's also possible that there are some long leads on the underside of the PCB that are shorting out--I'm not sure whether I should check any specific components for this kit in particular to diagnose that. I'm including some photos of the build--specifically the component side of the PCB and wired hardware. The hardware is still attached and I haven't removed the board to check the underside, but I will if I need to and there's no visible quick fix.

What about the module? Please snap a couple pics of that as well.

It would also be useful for us to see the solder side of both boards.

Added photos solder side of the PCB and both sides of the JFET module. I trimmed some of the longer leads on the PCB but haven't reassembled the hardware to check the signal yet (had to desolder the adapter jack to get at the underside of the board).

It looks like theres a solder bridge between the -V eyelet and a resistor on the module board. Also, you seem to have quite a bit of solder spatter. I'm not sure what you were doing to cause that, but you should get a magnifying glass and inspect the PCB for anything stray blobs of solder that look like they might cause a short.

There's also a lot of indication of poor solder flow. Blobby or irregular joints and partially filled eyelets are present, and I see several eyelets on the component side of the module where solder hasn't flowed through the eyelet and around the component lead. You should also clip the component lead ends down to the top of the solder joint and not leave "tails" protruding out of the PCB where they can cause shorts. My first suggestion would be to read through and apply the tips & techniques in this post: viewtopic.php?f=9&t=52188
