Caesar Chorus Ticking

I did a search of the forum but didn't manage to find anything conclusive. My Caesar Chorus makes a subtle ticking noise in bypass, matching the rate of the time indicator LED. I swapped out socketed components for others, even used a TL072, but the ticking noise is still there. Is this just an issue of pilot error in how the settings are dialed in or are there possibly noisy components I used that the circuit just doesn't like?

Thanks,
Jason

try moving your wiring from the in and out jacks to the footswitch to a different part of the board if you can, since the wires might be picking up some noise from your LFO. I have not built the pedal so I don't know if you have a situation where you can eliminate the noise or just take steps to minimize it.

That seems to have fixed the problem! Thanks! Good thing I went a bit proud with the cable lengths on this one, gave me plent-o of room to tuck them under the pcb! Good lesson learned for future modulation builds with potential to pick up LFO!

For anyone running into this issue in 2025, this fixed the issue for me as well. I had initially tucked the in/out wires from the jack to be tucked under the solder side (so when you open the bottom of the pedal they are hidden) but apparently this was causing them to pick up the LFO ticks. Moving the wires so they are hovering over the component side fixed it. Thank you!

This would work if I knew which component is the LFO :)

Anyway using shielded wire will eliminate all ticking.
