PedalPCB Gravitation - troubleshooting (bypass works)

Hey yall, relatively new to this hobby but loving it so far. This is my first build with a pedalpcb board but I’ve built a few vero board pedals and a pcbmania pedal. I cannot for the life of me figure out what’s wrong with my wiring on this board. I even connected the jacks, 9v and 3pdt to the board to eliminate my breadboard as a point of failure. Where I’m at now is the bypass is working and I can get a clean signal/led ON when I toggle the 3pdt. The only time I get a reverb sound is when the in and out jacks accidentally touched each other, not sure what that’s about. I’ve attached pics and I’ll link a video of the sound in the thread.

Thanks in advance!

Sorry for the delay, Imgur didn’t play nice so I had to upload to YouTube.

Also I forgot to mention my wire color coding in case it helps:
* Red = 9v
* Black = ground
* White = input
* Green = output
* Blue = bypass
 
A quick look and the soldering of the in/out/power wires at the top of the board looks very loose. I would make sure there's enough solder to fill the holes and also double check that nothing is possibly touching each other.

In general, you'll want to reflow and ensure all solder joints look good, with components having a secure connection and nothing potentially touching where it shouldn't (that may not solve your problem, but is good practice in general and will help down the road, if not in this case)
 
Thanks for the tips. Ordered some flux and am going to touch up the joints. I also did some digging and found a post about audio probes, seems like that might be useful in my scenario too so I'll build one. Will report back
