Moonshot Tremolo issue

[baol]

Hi everyone,
I send an audio signal in my Moonshot but I cannot track the sine after R2, I have the right signal between C1 and R2 but nothing after there. Nothing on IC1 input.
Any idea? What to check?
Thank you.

Post some pics. We may see something you can't

Assuming you’ve already done a visual inspection, the next thing I’d suggest is tracing the circuit and checking component values and continuity. R.G. Keen recommends printing out the schematic for this, and that has helped me immensely.

Like @BuddytheReow said, some folks here are great at spotting issues if you’ll post photos.

I know, I know, a picture would be helpful but I wanted to avoid taking the board apart from enclosure if possible. I replaced TL072 and everything worked perfectly but after few hours I'm in the same situation, so I guess I have something wrong that knocks out the IC.
does anyone have the correct values of the voltages on the tl72?
thank you

Don't know specific voltages, but I always start with the "known" voltages - pin 4 must be at ground/0V, and pin 8 at around 9V.
