Ok UG, I need some info

How hard would it be to install a zvex fuzz factory into a guitar (ala Matt Bellamy)

And how much do you think the customization would cost?
"There was a time you let me know
What's real and going on below
But now you never show it to me, do you?
And remember when I moved in you
The holy dove was moving too
And every breath we drew was Hallelujah"
-Leonard Cohen
Theoretically not hard at all.

Route out a cavity for the electronic/knobs/switches/battery and you're there.
我会关闭我的耳朵,和我的心; 我会变成一个石头
"I will close my ears and my heart and I will be a stone"
