resistor values for voltage divider, simple question

I tried searching on this, for what it's worth...

I'm interested in the remote switching described in the url below, which does not specify values for the voltage divider.
I know it's two equal-value resistors to get half of +V, but does it matter whether I use two 10K's or two 100K's, etc. ?

thanks in advance.

From what I understand, you balance current consumption and noise....10K would be lower noise, higher current, 100K the opposite.  The cap helps with noise, too.

I'd try it using 100K, and if that causes trouble go lower.  Generally I'll use anything between the two unless the circuit specifies an exact value to use.

I'm guessing you did not also read the article that tells you exactly how to do this:

People quit reading GEOFEX too soon.

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.
