Question about pots wiring

[SanderNijland]

I have a question.

I want to change some resistors in my pedal for some pots so i can tweak them op the spot. The idea is to solder the original resistor to the pot so i cant get a value lower that the stock one, only higher values are needed for this mod. But how do i need to connect the wire's? Just to lug 1 and 3 (when looking at the back of the pot) and the restor soldered to log 1?

Maybe I am missing something and for that I applogise but, if you connect a resistor to the pot this will increase the total resistance. It will also make the resistors value the pots starting point within the circuit.

As far as wires the middle one #2 is the wiper pending on whichever one you connect it to #1 or #3 will determine which way to turn the pot.

  Youve got it !
  Also apply the voltmeter/DMM to see what a pots range, value, and taper are.
  Taper is a little harder to tell with a DMM, but 'B' taper is linear, "A" taper is audio.
  Either type of taper provides an R value range, usually the R value and taper is marked, sometimes not, but the sweep of the audio pots R value range is 'curved', and most of the change in R value is 'bunched up' at one end, only small R changes per amount of rotation happen at the other end of the sweep.
