You can turn a linear pot into a log pot with the addition of a resistor from the output to one end of the wiper. Very quick to set up a spreadsheet to graph the response so you can choose the right values.

I need it to repair the LFO rate of a Moog Prodigy (someone replaced the 2.5 Meg with a 100 K pot so that it can only produce fast rates). Any help would be greatly appreciated.
