I'm not sure if the pot is actually 'doing' anything aside from acting as a lever so I don't know what the effective difference would be in functionality between a 10k and a 1k pot when using the dna board. Anyone have a tip?
DNA board, 1k vs 10k pots.

I don't think there is any difference in terms of functionality on the dna. It seems that, in order to allow use of different value pots, it basically just figures out the total resistance of the pot and gets the position of the pot by percentage. Pot turned all the way down = lowest setting, pot all the way up = highest setting.
If you take a multimeter and test the resistance on a 100ohm pot between the wiper (middle lead) and the + side when turned all the way down you'll get something around 0. Then test between the wiper and the - side you'll get something around 100. Turn the pot up a quarter way, between one side you'll get 25 and the other 75.

I tried em both along with a 5k pot when I was building mine, couldn't tell any difference. If I remember correctly the 1k seemed to be a bit more even across the range but that could just be in my head, all 3 worked fine.
The small trimpots should be a linear taper, but those big volume control knobs sometimes have somewhat of a curve. Been searching for a small pot that has a panel mount/doesnt need to be special ordered from the manufacturer. T'would be nice
