1 meg 100k concentric pot
I need some 1 meg 100k concentric pots, but the price is too high. I see that Antique Electronics has dual 1m pots. I can parallel a 120k on one pot and get very close..... will the taper get screwed up very badly for use on a Dano type build? The AE pots are 2.50

Re: 1 meg 100k concentric pot
Sometimes you can buy the value you need along with the dual and do some surgery to get all the right parts in the one pot.
Limiting will work, but I have very mixed results when doing it, for the most part. Theory is good. Reality isn't perfect.

Paralleling a fixed resistor across the outer lugs will get you something close, including taper, but if you need to have the two outputs varying in exactly the same proportion to their respective inputs, you won't get that.

I've had a similar problem. I did not find a source for reasonably priced. It is probably a custom order and your one-off is not of sufficient quantity.
Get something like this: http://www.smallbearelec.com/servlet/Detail?no=114 Buy the two values you need. Swap the rear pot elements and you'll have what you need. This is easier than you think. If I can do it, you can, too. Buy some extra's in case you need a do-over, so shipping doesn't eat into the total cost unreasonably.
I needed a 1K/5K pot for an oscilloscope and I amazed myself with a successful outcome.

There's a Fender bass that used a concentric (can't remember which one, sorry) and replacements are available. They are CTS so you can open them up and swap in any other values you like (got to cannibalize some other pots).

Fender'62 American Vintage Jazz Bass. Concentric and stacked. Wrong values, but CTS so you can change them. Getting the right knobs is a whole separate issue.

Re: 1 meg 100k concentric pot
Hang on, you said concentric, not ganged, so you want to control them separately? If that's true then it doesn't matter if they don't track proportionally. I'd go ahead and try shunting.
Re: 1 meg 100k concentric pot
I think Musicians Friend has the pots I was talking about. Maybe the knobs, too, IIRC.
