You should double check the schematic for R1 - it doesn't make much sense to bias the + input through R3, then connect it to the ground.
Also, pins 10 and 5 of TL 064 should get some bias from somewhere.
Double also, you may have missed a resistor from pin 14 to pin 6 of TL064.
Other than that, nothing beats the old audio probe in debugging.
LATER EDIT: try to use easier to edit/view formats like png/gif/jpg, instead of pdf, when posting things not meant to be definitive.
