Hi friends,
I'd like to purchase some 500K reverse log pots.
I know, Small Bear etc etc, but the shipping fees are more than the part itself, as I am from Asia.
Any kind soul has some spares to let go of?
Thank you...

If you take a 1M linear pot and parallel it with a 1M resistor, the result will be a antilog 500k.

Futurlec.com has some too.

Modman, thanks for the tip! But I still need help with true reverse log pots. Here's why...

I read the "secret life of pots" site (who hasn't) but unfortunately it didn't work for me on my Dist + DIY.
I found a good explanation why: http://music-electronics-forum.com/t3084/#post165321

Yeah, communication is not their specialty. But you can order right away:

to order search again using the part number:

Part No.: POT500KC
Description: 500K Anti-Log Taper Potentiometer
Info: In
Stock: yes
Price 0.65 USD

If you find potentiometers cheaper somewhere else, let me know. Even if you don't need anything, you could take it as a opportunity to stock up some common pot values.

Hey guys,
Here's an update on my situation.

I managed to source 500K audio log dual gang pots, for USD 0.80 per piece.
I think it is cheap, considering the normal pots are valued at USD 0.65 as updated by Modman.
Anyway, that's what I used, just one of the pot rows, wired it the other way around - swapped lugs 1 & 3.
It works, and in a funky way - it's reversed

It's nothing new. Many have applied this technique before.
I am just updating my situation here, that's all...
