Wah pot's measuring weird

[Keysershades]

I have a old Jen wah and a "new" Vox wah, and both of the wah pots is measuring weird.. The Jen wah i'm measuring to 4.47 M Ohm and so does the Vox... Both of them is broken ?

grammar

Really ? So if i learn to speak better English my wah will work again ? Not everybody is American/English speaking my friend... You know there is other countries right ? If my post does not make any sense to you, i am happy to rewrite it just for you... But please tell me so in a nice way.

If you disconnect the wires from the pot and read across the outside lugs of the pot with your meter, you should see the actual pot value.

You can also check your meter with a known value resistor to make sure it is okay first.

i was going to say the grammar is killing me but the first post didn't go through.



most people who speak english first are usually ignorant in not accepting another language, so you're lucky not to fall into that category.


i can't speak american though... that's the original bad english.


anyway... just like Arn C. says, there's nothing more to it.


i didn't mean offence...

  The wah potS measures funny?, seems clear enough to me the question is 'why?'.
   Whenever I see a "Plural-misread" [more than one component reading outside of their respective ballpark ranges] the suspiciion there's something in common with both 'ok' components which is throwing the reading off.
   Sometimes a bypass resistance path is easily found on the schematic, or by lifting a pot connection or two and comparing measurements of the in-circuit resistances to the pot-only readings illustrates the proportion of R's across the pot only to pot with circuit attached.
    But first: read a resistor color code in the range of the 'wierd measurement', and another resistor value in the ballpark of the pot.
  Try a fresh battery in the DMM !

Wow
Darren, sligh remarks. Come visit the beautiful USA and I'll buy you a beer.

I would disconnect the pots in question, attach my multimeter to #3 and #2 lug and rotate the shaft through. Depending on what value the pot is, it should go from 0 to 100 K or whatever the value is. If it does then you have other issues. Strange that the same issue is with both petals...Did you do some work on BOTH of these pedals and wound up with this strange occurence?

dunno. didn't like the assumption that i was american... just because you guys own the internet... and... and... everything else (:


back on topic.... i used to measure all alpha pots before putting them in amps and i swear some of them read 130% of the marked value...

that is why we are buying you a beer, we can afford it since we own everything
