Well this thing still isn't working. I've gone over it a couple times, still can't find the issue. I have to crank my amp to max just to hear anything out of the circuit, and when I do it just sounds clean. The voltage on both sides of the LDR is 0V. The +, - and output of the op amp is 4.5V as it should be. Doesn't appear to be anything wrong with that. No signal is apparent on either input of the op-amp. Something is going wrong with the caps and resistors.
