pi threshold potentiometer sensitivity

[beachnut]

Hi all. I want to maximise the available adjustment of the threshold pot. What I would like to know is it possible to have two pots in series. One to get the adjustment close and the other for finer tweaking. If it is possible what would you recommend the values of each should be. Thanks.

10 turn pot
Find them on ebay.
I use the one that looks like a clock, works excellent to change PI frequency. If they don't have to be waterproof.

I used a silver colored mylar polyester decal sheet made to be used in Laser printers.

Set the printer to transparency print mode. Fuses the toner hotter so it can't be scratched off.
Or you can take the front panel file after you export it to a .bmp, jpg to a local printer that prints decals.
