SOLVED Kliché Mini - Gain works weirdly inverted

Hi everybody,

I am building a Kliché Mini at the moment. Unfortunately, the Gain poti works not as expected.
If it is turned most left, I get the most clipping. The further right it is turned, the less clipping can be heard. Instead it gets dark.

I already double-checked the resistor and capacitor values.
The voltage supply of the ICs seems to be ok as well.
I have no idea what to try next.

Here are the voltages of th ICs:

IC1 (TL072)
1 = 4,73V
2 = 4,73V
3 = 1,29V
4 = 0,00V
5 = 4,62V
6 = 4,72V
7 = 4,69V
8 = 9,46V

IC2 (TL072)
1 = 4,76V
2 = 4,73V
3 = 4,67V
4 = - 8,98V
5 = 4,68V
6 = 4,73V
7 = 4,69V
8 = 17,0V

IC3 (TC1044SCPA)
1 = 9,46V
2 = 4,95V
3 = 0,00V
4 = - 4,29V
5 = - 8,98V
6 = 4,73V
7 = 4,33V
8 = 9,46V

Thanks a lotfor your help.
Greets Ralf
