Huh? I must have flunked physics without knowing it. So you can adjust a potentiometer by attaching a wire?

I don't believe it is a wire. I think it is something like a speedometer cable. The outer shell attaches to the mounting threads of the pot and an inner wire attaches to the shaft. The pedal through gears causes the inner wire to rotate.

It shows, Keith!

I see another objection - the shaft must turn with very little force, otherwise the momentum will just twist the cable. Not all pots move as easy as that, I would think.

Same idea as remote controlled hi hats that drummers use for a second hi hat..from an engineering point of view it is not that complicated, as keith h says, gears to rotate the inner wire from the vertical movement..car throttle comes to mind.

I bow to your superior knowledge (I do).

Still I wonder why they don't just hook up a pot in a footpedal to replace the pot in the stompbox. I bet it would be cheaper too. ;-)

One problem I see with this is the potential to damage the potentiometer. I don't see any thing to keep the pedal from exceeding the range of the pots movement. In addition I would expect the pedal to put much more force on the stops than a hand would.

I'm with Adriaan. Why not buy an old Wah Wah for the housing and move the stomp box guts to it?

I'm just glad to know that it is made of real metal. That says it all for me.

I'll give it a shot on some cheap pedals first, maybe a little mod for limiting potentiometer throw might be in order, thanks for the inputs.
..and as noted, tenderness will be needed I bet...might be more of a studio thing if it has the power to tear up pots.

I'll see soon.
