Many units use linear pots by default.

[The correct type for this type of circuit is a W-taper] -- Just a few minutes ago I found some miniature "Fader Sliders" that are available with a "W-taper" and they're small enough to easily fit onto a "500-Series" front-panel horizontally!!! They could be bigger (i.e., "longer") if they were to be mounted vertically, perhaps in 2-sets of 3-faders each. That is a future decision yet to be made.

I am contacting the manufacturer right now as I am writing this response in order to obtain some additional information on them. Kind of like this:





Kind of like this.....only with half the number of sliders:

I used thousands of these 50 and 65mm faders with W-taper. I had to order them with MOQ of 10k.
I think the only possibility to get them in "DIY" quantity is if they are used by a manufacturer and spares are available.
The problem is that most manufacturers have phased out graphic EQ's.
API audio use the 25 (30?) mm version in their 500-series. They may be available there.
