Thanks Johnny; I was aware of that. The cutting I was referring to was the big hole that folks sometimes cut into the side of the guitar for the control panel. Lots of guitars come with these already installed, but some people will retrofit these to guitars that didn't come equipped with them from the factory. Either way, I don't like them (talk about sullying a beautiful instrument for the sake of the pickup!); I tend to think it's better to do minimal alterations to the instrument itself, and go with outboard controls.
