Very quiet Proctavia

[Gretschocaster]

Hi all,

I picked up a non-working proctavia recently that wouldn't let any signal through at all whether bypassed or not.  I resoldered the connections on the stomp switch (which looks to have been replaced previously) and the jacks and now I have a bypass signal and I can hear the effect when engaged if I turn the volume up as loud as possible and jack the volume on the amp, but it's obviously not useable like this, it's on the edge of audible.

Any ideas what it might be?

Well, I resoldered a bunch of joints that looked a little rough, and now the effect works but the I lost the bypass signal somehow lol.  Guess I got a bad joint in there too.

Since bypass signal was virtually silent before the repairs and it is totally silent after the repairs, it seems highly likely that the bypass signal wiring is off.
