Source for a 500kC pot with a wah gear?

[drezdn]

There's a phaser pcb I'd like to mount in a wah treadle, but I can't find a 500kC pot with a gear. Does anyone know where I can get one, or how to add the appropriate gear to a regular 16mm pot?

There are push on wah gears for splined or 'D" 1/4" shafts. Maybe with a nice industrial strength PEC pot.

Your harder task is going to be finding a 500KC pot that will "fit" in a wah shell

When I did this same thing (but with a vibe), I went with the Dunlop ECB024A Hot Potz Cry Baby Potentiometer – 470k. It's not quite 500k, but it was as close as I could get. I believe it's a log (A) taper, but you can wire it backwards.

ETA: I bought mine on Amazon.

I'm pretty sure all of the Hot Potz II tapers are (B) Linear. Maybe you can use resistors to get the curve you need though.

Small Bear has them with a more detailed description, including that it is an audio taper.

Missed that one. I don't surf SB website very often though...
