You cut the trace into pin 3 of the 4052 and insert the 100 ohm
resistor. I didn't go look at the board, but I seem to recall that it
is a long enough trace that you can cut it and brighten the traces on
either side of the cut and just lay the resistor on with short leads and
solder it in.
BTW, I noticed that I used a 75 ohm resistor instead of 1K on the three
outputs, because I use this to drive 1 volt/octave inputs. 100 ohm
would work here too, I just had more 75 ohmers lying around.
