Can I get a specially ordered reverse audio curve?
I've made some stompboxes that use a reverse audio curve as a gain pot.
Crowther Audio Hot Cake, Sansamp Bass Driver, Darkglass VMT / B3K...
All of theses are have same problem.
When the drive pot is turned, the amount of gain is almost unchanged, but suddenly changes from the last 20%.
I don't compare to the original, but it seems to work pretty well on YouTube samples.
Can I get a specially ordered potentiometer that can be used for circuits with these symptoms?
It may be difficult, but it would be better if you could tell me 9mm mini pots like below because I made mini size effectors.

Lots of manufacturers make reverse logarithmic potentiometers. Look for reverse log, anti log, reverse audio taper etc. - they should be rather easy to find.

You can also make your own log, anti-log, exponential, reciprocal or almost any other curve by the addition of "tapering" resistors to linear pots. There are lots of descriptions of how to do the calculations on the interweb!

It seems a reasonable idea. Can you recommend the taper calculate tools or sites?mictester wrote:You can also make your own log, anti-log, exponential, reciprocal or almost any other curve by the addition of "tapering" resistors to linear pots.

Thank you! It will take a lot of time to read because of my bad English ability, but I will read it carefully.ppluis0 wrote: Take a read on this link: http://www.geofex.com/Article_Folders/p ... tscret.htm

The easiest way to use an ordinary logarithmic potentiometer is by simply swapping 1 and 3 legs.
You will get a reverse logarithmic potentiometer, just it will work in the opposite direction.
