Newb pot question...resistors

[momo]

Sorry for this simple thing, It sure is not for me

So I need a 1K pot...ive got a 300 ohm one....do I add a 700 ohm resistor to the center lug(wiper), or on the hot input?, surley not on the ground lug?
I have a linear pot and thats what I need. So is there a resistor placement strategy that keeps the pot linear?
I read R.G's secret lives of a pot write-up. But my brain right now is tired and it seems so simple
This would be great, I could use old CTS pots.
thanks

You can add a resistor to the pot at the bottom or top of the pot. This will leave you with a 300 ohm variance either at the top or bottom of the pots travel. It depends on what the pot is used for.The resistance is 1K total but you can only alter it by 300 ohms.
Picture this:
Gain pot control with 300 ohms pot on the top and the 700 ohm fixed resistor connected to the bottom (ground) . The 300 ohm resistance will allow you to turn the gain down by about about 30%. If you put the 300 Ohm pot at the bottom you will be able to turn the gain down all the way to zero and raise it up to 30%...
Make sense?

Ah,,,,yesss that makes all the sense. I now understand why some test builds were not using the proper range/gain!
O.K, so ill order a true 1k.
thanks!
