Boss FV-200 Volume Pedal?

[Arn C.]

Howdy Folks!
   Anyone have a wiring diagram for this keyboard volume pedal?
It has a 20ka dual pot for the foot controlled pot and a 20ka dual for the other volume (center is min vol).   Someone gave this to me and gutted it a bit.  
Any info would be great thanks!

Peace!

Center is min vol?

I did have a schem for a Boss mono volume pedal but can't find it.

It is basically the foot operated pot set up as a normal volume pot with the other pot on the ground side of that, so you can vary how close the signal gets to zero.

Look at it as the second pot is a preset for the minimum level.

I'll keep looking for the mono schem.

Update
Got the schem I was looking for. A Roland EV-5. I'm guessing it's not a million miles away from a Boss.

Hope that helps.
