Ticking noise from guitar pedal attempt
C7 is back to front. Its positive side is at +2.5 V and its negative at +4.5 V. Also the TL074 really needs a supply of at least 10 V (see data sheet). The common mode voltage of the op-amp needs to be at least 4 V above the negative rail too. This is not the case in the second stage. 
An LM324 might work better although its audio qualities are poor (crossover distortion) but you could try it for starters.
