well i installed a xeno gc and the pot is off a bit. i got a multi-meter but on modthatcube they said you need a screw to adjust it. what kind do i need?
The screw is in the cube itself. Look at the pictures provided and you'll see what you have to adjust.
I suppose you could just get a paper clip or some other type of thin metal and flatten the tip with a hammer so you could use that instead.
