LMNC MS20 Filter Low Output

After finally finishing my “inspired by LMNC” MS-20 build and fixing a couple of PCB glitches, I was a bit puzzled that my notes said 10k for the input resistor, but my schematics had a 100k there. Trying to figure out where I got these values from, I checked some other schematics, and it seems like the stripboard layout uses a 10k resistor on the input (as does Schmitz), while the performance layout uses 100k. These resistors form a voltage divider with a 220 ohm resistor, so for a full 10 Vpp…
