Wavefolder input level

Hi all,

first of all I must say, that I'm not an geek in electronics, but still build modules, so excuse my primitive questions.
I finished the wavefolder and selected an 680 ohm resistor to the position of R21.
In the layout it says I can use a 330 ohms resistor, depending on the inout level.
Could someone explain please what the difference between those to means??
Does it fold more or less or can I simply input higher/lower audio??

Thanks

Correct me if I'm wrong as I'm still a noob, but as far as I understand R21 and R18 determine the pp level, cp. this thread:

So with the values given by Yves you'll have a 20V pp signal ...
