I just finished watching this documentary.
If you are into electric guitars and their effects, this just might be a must watch.
It was released on VuDu on April 30th, its about 2 1/2 hours long.
Showcases the artists, their music and the innovators that helped to shape their sound.
I have no doubt that you will recognize many of the names.
