R1 and R10 only appear to be on the etched version, not the manufactured board, so I'm going to assume you etched your own.  Both resistors appear to be pull down resistors at the inbut of each half of the dual circuit.  In a typical pedal you would expect to see a value of about 1M there, but I don't think they are required in this particular build.  You may safely omit them.  By jumpering them, you are sending 100% of your signal to ground the second it hits the board, hence no sound.

Good luck!

Yeah, just remove the jumpers and you should have it.
