At least, I can affirm the input circuit is identical to the EC2000 DMM schematic : R1 : 2.2M, C1 : 0.1, R2 : 100k, R3 : 22k, C2 : 27p (ceramic),..., 6 x 2.7n poly caps (yellow), and so on...

Thanks for those! I wonder what the LQFP chip is for... clock and taptempo and division math?

Yeah, given the 3005s (socketed even!) up top for the core delay function, I'd imagine the digital processor is all for the timing and expression pedal control set up.
