Electrovibe crackle

Hello all, I am new to the forum and to PedalPCB although I have build pedals from other sources. I thought I would try my hand at the Electrovibe as it was a pedal I was interested in.

Its all working as it should from what I can tell. I am getting pulsing all the pots and trimpots work the only thing is I am getting a crackle on the output sound. The crackle goes away if I turn the gain right down. I have tried tracing this with the audio probe, however it is difficult to pin point. I am not sure what component I should be looking for that would cause this? Voltages seem ok, although perhaps a little lower by 1 or 2 volts.

Any help would be great please?
