Theremin controlled Volume "Knob" in my guitar.

I plan on taking the Tone knob out of my guitar and replacing it with a Sensor of sorts in which When I pull out my Volume knob, the sensor becomes active as a Theremin-like volume control. This being that the closer ones hand is to the sensor, the lower the volume, and the farther you are the louder you are until original input gain.
This hopefully would be a useful tool for Swelling, Manual tremolo, and Feedback loop control.
Does anyone have any ideas on this, or any idea on how I would go about doing such?

Photoresistor?

The problem is that light control would be too difficult to manage, as I intend on using this live
And During Slower songs where Manual tremolo and swelling would be used a lot, chances are they will dim down the lights.
I was thinking there is a way to take the tone pot, remove it from the circuit, and then in turn use it as the "pole" on which the theremin senses.

Then you're looking at an active circuit... and theremins aint simple, even the simple ones... how about a slide pot instead... that'd be easier.
Otherwise you want to build yourself an Z.Vex trem probe into your guitar... then have a copper scratch plate.

It'll run ya 270 but with a volume pedal and some delay. your volume knob can be used as a theremin. and you get a nice fuzz pedal to boot.

Not at all what i was looking to do if you read above but still rather intriguing
Does anyone know of a guitar - mountable battery powered Light source of small stature?
I might have to go with a Photoresistor + Light deal.

Yeah an LED and a Watch Battery with a switch to break it.. bout as small as you'll get for mountable light source, look for the battery type with the best mA hour though and use that... probably AAs, you might need a resistor in there too depending on your LEDs rating and to limit its current draw.

I might go for taking apart one of those lights that are used for Photoresistors in pedals such as the peep, eye of god and the sort.
I see them on boards very often on HCFX, anyone know what i am taking about?

Doh! just re-read the post.

Sounds like you want a Zvex Drip Guitar but with a trem probe in the pick guard instead of a wah probe.
