10-20 LEDs in electric guitar powered by coin cell and with color/function control?

Hi,

I am trying to figure out what is possible or not for a project. I would

like to install 10-20 small LED lights into the control and pick up

cavities of an electric guitar, and I would like those lights to be powered

by battery, ideally coin cell(s). Also, I would like to be able to control

the function and color of those lights. Is this possible?

I have attached a photo of the guitar with blue dot graphics to indicate

where lights may go.

Thank you!

Matt
