What's a D taper potentiometer?

D taper pots are usually very similar to log pots but with a slighty more aggressive slope. I don't think you would notice the difference with most audio applications so you can use them in place of standard A or log taper pots.

I've tried to measure it with a DMM, and it looks pretty weird. The clockwise rotation (measuring so that there's 0ohm in the counterclockwise extreme) has next to no effect on the resistance up until the last quarter of travel.  Isn't that a reverse log?
marking on the pot is D1Mohm

digital taper.  goes up in steps, total of 256 steps per rotation.

What you described is a normal log pot. A reverse log pot would have a rapid increase early in the travel.

Ok.  Me - moron, you guys are right. *shy:)
