    You want to remove the knob? You'd have a P bass missing a knob.

    You want to remove the TONE POT? Assuming you did it correctly you'd have a bass that sounded just like it did with the tone control turned all the way up, since passive tone control is cut only.

    Removing the knob? Get a little allen wrench, loosen the setscrew and it comes right off.

    Wait...I bet you mean removing the tone POT, dont you?

    It wouldn't be difficult to do and would make your sound a tad brighter than it would with the tone pot wide open.
     
  7. There should be no problems, the tone pot on the Fender P at my college is not there and it plays and sounds like a dream, I wish they would let me buy it...
     
  8. why would you do that?? just turn it all the way either way until you find your spot. BAM! Instant no pot effect.

    That wouldn't work becuase the pot itself has a resistance.
     
  10. Personally, i wire my basses with push/pull pots that allow me to bypass the tone control when i want to.

    A tone pot works by varying the amount of signal that feeds the capacitor. The less resistance on the pot, the more signal the capacitor receives, and thus the more high frequency content it removes.
    Having a pot turned all the way up is not the same as bypassing it. There is still a resistance of 250K or 500K from the signal to the capacitor. By removing the tone control, (obviously...) the capacitor is not getting any amount of signal at all, so your tone is much brighter.

    If anyone is interested, here is my diagram of a push/pull bypass switch for a tone control.

    Another approach is to use a:

    Potentiometers
    (1) 250K, Solid Shaft, "No-Load" Potentiometer (Volume or Tone)

    Hey guys. Would much re-wiring be needed or could i literally cut the wire that goes to the tone pot? I'd personally like to keep the knob (meaning it'd be easier to keep the pot too) but have it just...not work. I want brigher tone and this sounds like a good solution. :help:

    That would work, had mine like that for years, only put it back in last year when i realised I was too old for punk now.

    It will work. It wont be all that brighter, but a little bit.

    Replacing the volume pot with a 500K or 1M will get you ever more brightness.

    I have a fender TBX tone control on my one passive bass. That works nicely for a bypassed tone control.
     
  17. So I have a question along this line. I just had a bartolini preamp put in my pbass with a push/pull knob for switch from active to passive and a stacked tone pot. The stacked pot only works in active. My question is: When i'm in passive is my tone like having the stock tone knob all the way forward? Thanks
