Success! Touched up pin #13 on the opamp from the component side, output problem solved. Tried touching up R32 from the component side, but no change in the relay, so I took the board back out and re-soldered pin #13 on the socket (which admittedly looked like I had either missed it or barely got much soldered flowed on it); relay switching fixed. I now have a functional, kick-ass pedal! Thanks for the help!
