    I am not sure I really understand how pot value works for the gain control in a circuit. I'm hoping somebody can explain like I am 5.

    I modified an SD-1 and changed R6/C3 to give the pedal more gain. It still has the stock 1M pot. I have all the gain I need at about 12 o'clock. Am I correct in assuming that if I change out the pot to a 500k it will have the same amount of gain at max but a more useful and precise sweep of the pot?
