HELP: Effect sounds great, bypass signal EXTREMELY weak. Thoughts?

[elenore19]

I mailed my friend a pedal, it worked perfectly before mailing. Now my buddy got the pedal. The "on" signal works great. The bypass signal however he says is very very faint. So faint that the tuner pedal doesn't pick up a signal to show what notes he's playing.

My thought is a bad switch. Could it be anything else?

What pedal is it? One you've built or a commercial pedal?

Maybe an ic or transistor that fell out of the socket? A loose ground touching something? Pics would help

Bad switch or the wire loop bridging the in/out at the bottom of the switch has cut loose or is intermittent.

I would say solder flow on the stomp, this happened to me also. The signal comes in, goes across the switch and right back out, it would bypass the board entirely, so even if everything fell off the board, bypass will still work.

Thanks for all the help guys.

It's hard to debug a pedal with someone who isn't a builder and also has the pedal very far away so I can't look myself...
We ended up finding out that with the cables plugged in the wrong direction, the bypass worked. So something was fishy. didn't make any sense. He then found that any contact with the bottom right lug of the switch made it work. I had him resolder the joint, and voila! It worked!

Thanks for all the help. Somehow I guess the solder joint became "cold" in transit.
