250k/500k stacked pots - Which is on top?

[pattyløve]

So I am wanting to install a Vol-tone stacked pot to accomodate for my bass's 2 pickup, 2 knob setup (vol, vol/tone stack).
With the fender and CTS stacked (500k/250k) pots, which pot is the 250k and which is the 500k? Common sense tells me the bottom should be 500k.. but I have no way of telling.

wouldnt it be best to Measure the Value
The way its worded i would say Top one was the 500K and bottem 250K .. 500K/250k

Oh okay, thanks!
If that's the case, does anyone know where I can get some 250k/250k stacked pots?

Anyone else have any more insight into this?

Sorry its easy to make mistakes, so its always suggest you check it before doing any thing

I believe they are indeed designed with the top knob being the 500k and the bottom 250.

I don't know of a source of CTS style 250/250k stacked pots (i'm pretty sure they aren't readily available if at all), but it is possible to switch out the rings on a CTS stacked pot with a 250k ring from one of their non stacked pots without much effort. They come apart and go back together very easily and all the parts are mostly compatible. If you are using one of the Fender-branded CTS stacked pots, you can also actually take it apart and just switch the rings on a 250/500k pot. On a non-Fender standard CTS stacked pot you can switch the two rings, but may have to widen the hole in the middle of the bottom ring slightly with a small file (which is super easy!).

I have taken apart and modded tons of CTS brand pots over the years with no problems, but I'm not sure if this is possible with other brands (I know some aren't designed in a way where they can be taken apart at all).
