Sounds like it could be something to do with your power supply the only way to know for sure is to either get a 9v regulated and filtered power supply or use a battery with it being present at pin 3 ie audio into the op amp that tells me it’s there at the clean signal input and is then being amplified

Check if you get it on the pcb input pad and R1 and C1 that’ll let us know if the noise is there prior to going into the effects circuit
