Optical volume pedal with a sharkfin-alike light control

[Cortexturizer]

Googling got me nowhere. I want to make a volume pedal since I already have an enclosure that I am not using and I do need a volume pedal. I was thinking something like Morley pedals that use LDRs and a plastic mechanism in the form of a sharkfin that controls the amount of light being cast on the photo resistor, I had a Morley wah before and it worked the same way and I remember how it looked inside.
The cool thing about this is that you can make your own taper the way you want it, by making the empty space on the plastic sharkfin the way you want.

It doesn't have to be a sharkfin controlled volume pedal, if someone has a link to an optical volume pedal project please send it to me. Would be really grateful.

The ONLY reason I need a volume pedal is because I possess two guitar neither of which I can use for volume swells because the pots are just too far away. Damnit.

There was a thread over at DIYstomp from a guy asking what to do with his new 3D printer and this kind of this would be ideal.

The George Dennis brand wah and volume pedals work like this as well. I should think you'd be able to rig up something similar with some type of industrial adhesive (and run the LDR/LED off the main board next to where the fin will be).  But maybe I'm oversimplifying things. I haven't seriously attempted this kind of  thing, so I might be way off.

Hm, anyone else?
It's really annoying having a need for a volume pedal just because you played a couple of gigs with a guitar that had volume pots much closer to the strings.
I really like doing the volume pot thing but I've finally stopped the GAS for guitars and settled for an SG and a Tele Deluxe so it's cheaper to get a volume pedal or in this case build one than to develop a need for another guitar

don't know if this helps, but Morley posts a lot of their schematics here:
