What kind of pot is this?

[BuddytheReow]

SBP sent me a goody bag and am finally going through it. Can anyone tell me what kind of pot this is? It's a 16mm pot, but just odd labelling...

Did you meter it?

Looks like a reverse audio taper 1M. Better send it to me for disposal.

Did you meter it?

No not yet. I've only had 10 min go go through everything on my kitchen table. When I have a moment I'll put it through the DMM

The first 10 probably means that you get 10% of the total value when it's at the half rotation point, measured between the CW lug and middle (it's the opposite of a log pot, which would be 10% measured from CCW to middle)

RD1M = Exaggerated C1M
RD sometimes styled as 10C

A=Audio/Logarithmic. 15% resistance @ 50% travel.
B=Linear. 50% resistance @ 50% travel.
C=Reverse Audio/Logarithmic. 85% resistance @ 50% travel.
D=Steep Audio/Logarithmic. 10% resistance @ 50% travel.
RD=Steep Reverse Logarithmic. 90% resistance @50% travel.
W=Logarithmic first half, reverse logarithmic last half.

Thanks. With my DMM it’s a C1M with an odd taper

A=Audio/Logarithmic. 15% resistance @ 50% travel.

I thought the most common, garden variety log type is 10% at mid travel. Is this not the case?
