Pot question

Discussion in 'Pickups & Electronics [BG]' started by chalie, Jul 21, 2012.


  1. Hi,
    I found the impedance measure of my original pots on my 1979 P bass are around 850k (which should be around 250k). Should I replace that.
    Thanks for your advise.

    Those are probably 1 MegOhm pots. I don't know that there is any particular reason to replace them unless they are giving you problems of some kind.

    Did you unhook the pot from the circuit?
    If not you could be measuring more than just the pot.

    You made two threads for this question?

    No intention to hijack this, but I'm wondering what value pots
    onemight put into a '51 style P bass.
    And...are noload pots any good, as far as you know-is there a better way to bypass tone and volume pots, in your opinion?

    Thanks! :)

    250k.

    No load pots are only for tone controls. You can use a push/pull pot if you want to bypass the controls.

    Thanks very much!!
    :)
     
  8. Hi, Its say 250k and its original pots from Fender too
     
  9. It's not a Chinese pot and it's not in specs? Imagine that!

    A 1K pot is too bright for me and I would remove it in ANY brand if it was that far out of specs. Even if the knob didn't fall off, it's not 'right' to me.

    Go get a 250Ω and get that funky-down-deep sound that the bass is so famous for. :hyper:

    You may want to check your units. :)
     
  11. My 'units' are fine thanks.

    Oh - did you mean my basses? If so, never mind.

    Your unit should be M, and not k. :D

    A 1k (1,000Ω) pot would be ultra dark sounding with a high impedance pickup!

    His pots (850k or 850,000Ω) are closer to 1M (1,000,000Ω)
     
  13. OK - before sufficient coffee and there's a Grand Prix on TV right next to me.
     
  14. That wasn't the kinda question I clicked on this for:p

    That will do it!

    I can't form sentences and have poor motor skills without enough coffee!
