Befaco Kickall - waveshape issue

Author Befaco Kickall - waveshape issue
timequake
Hi,

a few months ago I build the Kickall module. Today, the module started to behave weirdly - when turning the SHAPE pot fully CCW the waveshape is not sine but a squarish souding wave. When I start to turn the SHAPE pot CW it becomes gradualy a sine - at about 10-15 %. From those 10-15 % onwards it behaves as it should.

Did anyone had this issue? What could be wrong? Already checked for shorts, checked the solders, changed all ICs, except the 3340.

Any help will be greatly appreciated smile

There is the audio (starting at fully CCW turned SHAPE pot):
