Dumb Collosalus cap question

[blearyeyes]

Since this pot is wired as a variable resistor in this circuit with pin 1 floating, isn't there a way to wire it to work in reverse?

I'm hoping some day this perpetual state of electronic confusion lifts and I have an Ah Ha! moment.

Wired backwards, the pot will be the right taper, but it will work backwards, that's how the pot works.

You can use parallel resistors to manipulate a pot but you can never completely change how it works.

Think of a volume pot, you have pin 1 to ground and 3 to the signal, 2 is the output, you turn that round, the volume is now going to decrease as you turn it up/clockwise as the signal is still being shunted to ground, just in the opposite direction.

If you have a linear taper, it will be equal across its taper wired either direction if you have an audio taper it will work in a logarithmic fashion, wired backwords, that taper will be reversed but the action of the pot is also reversed.

OK thanks, that makes sense...
