I'm after the following:

dual/double reverse/inverse log potentiometers 100k and 2.5k ... I had limited luck finding 100k and none whatsoever re: 2.5 k

any suggestions as to where i can find these ???

The 2.5k is going to be a problem. Look for "audio taper" as well, they are really close to a reverse log.

I dont think log (audio) taper is the same as reverse log unless you want to turn the knob the opposite way.

Try Omeg:

Conductive plastic, small minimum order, good prices.

You are right. I always think that Log and Audio are reverses or each other for some reason. (Probably because the graph they always show for the reverse audio taper looks like a log plot).

The other thing you can do is get a 2.5k linear and use a tapering resistor between the wiper and the Clockwise leg. Like a 500 ohm for a 1/5 tapering resistor or a 412 or 422 ohm for about a 1/6 tapering resistor
