So for the last year I've been dreaming about how I'm going to make my first guitar, and I think what I want to do is build a modified strat style, witha twist. I was thinking of routing out the rear top of the body and building a cover for it, putting my electrical mostly in the large cavity, but also cutting an f hole in the top, am I gonna have any feed back issues or any other foreseeable issues that I am over looking? Thanks
