He guys,
I'm about to finish my Chunk Chunk today, and one of the things still to do is putting a resistor across pins 1&3 of the 5kB mid pot (as mentioned in the doc). After looking at the schematic and reading "The secret life of pots" over at Geofex.com, I was wondering if I should put it across 1&2 instead of 1&3, since in this configuration 1&3 doesn't seem to do anything until the pot is rotated CW completely. Or should I put it across 2&3? I tried modelling the resulting resistance in a spreadsheet, but that didn't really clarify anything.....

putting it across 1&3 parallels the pot with the resistor (5k1 in this case) you put on it, dropping its value completely down to 2.5k.
I'm not sure what putting it across 1&2 would do.
if you put resistors across 1 + 2 and/or 2+3, you change the taper of the pot. it's possible to turn a linear pot into (an approximation of) a log pot, for example.
