    I have searched Mouser, Digikey and a few others with no luck. That's not to say they don't have it and I just couldn't find it.

    I'm looking for a dual pot that has an inner and outer shaft to control each wiper separately. All I find have each wiper controlled by a single shaft, turning each in unison. Below is a pic of the type I am talking about.

    THANKS

    Try searching for stacked concentric pots. I found lots of them.

    Thanks. I looked through, Mouser, Digikey, MCM, Jameco and Full Compass and didn't find any. The ones I found on a web search are mostly for guitars and are B taper (audio). I would like to find A taper (linear) and in conductive plastic.

    This is for a 3 band parametric EQ I am looking build. That's 9 pots x 2 for a pair of EQs. Front panel space gets filled quickly in a 1U rack enclosure. I might have to go with a 2u rack enclosure.

    Given everything, I have decided to go with a 2U rack enclosure. Which means I can use some nice ALPS plastic pots.

    Thanks for the help.
