Sounds like your technique needs to be refined a little. It should only take a second or so to make a good solder joint. Keep your iron’s tip clean and tin it before each solder joint. This will promote good heat transfer and the likelihood you’ll have a quality solder joint when you’re done. Since the eyelets on BYOC boards are thru-plated it is difficult to keep all the solder on the solder side of the PCB. Flow thru isn’t necessarily a bad thing as long as the solder that flows thru doesn’t form a short on the component side of the PCB.
See this thread regarding checking your stomp switch’s functionality.

To trace the signal thru the circuit will require a signal probe. A probe is nothing but a glorified capacitor and some wire and a connection to an amp. BYOC offers one in kit form or you can make one from an old instrument cable you don’t need anymore.
