really cool! Never even heard of this pedal.
The C19/R44 combo seems off. Can you verify the value of C19 is actually 8.2nF? 8.2nF and 1.2k would make U1a a unity gain buffer for most of the audio range...

Yes, it is correct. Every component in the original pedal was and-measured. Confirmed by comparing the trace also done by Robert (@PedalPCB).
