Thanks a lot, mates, I think I understand all your answers. I know it's different depending on the side you install it. I have a CrunchLab I love turned opposite because it is loaded in a mahogany axe.
I didn't realize at first it has a double pole row, so it will slightly unmatch my original guitar aesthetics, but I think not so much:

But anyway I have a bad feeling about it. First of all, though some other people told me not to worry and don't even remove the strings, I'm going to do what you suggest, no strings in the way. However, I am very reluctant to leave my bandmate (or almost anyone) touch my guitar. It cost a lot, I am a bit a maniacal of cleanliness and order and I treasure it like my baby, you probably know what I mean :) buuut my soldering skills are totally nonexistent and he is a electronics wizard (though very clumsy and dirty), he fixes TVs and whatnot.
In short, I think it is going to be a pain and after all I'm afraid I won't like the Cpig either and probably have to change it back. We'll see. Maybe I take a pic of the reverse later to show you and make sure I understood the way you told me I should install it.
I was playing yesterday with it (Cbomb yet) and I almost like it in my Blackstar, darker amp, but it makes me cringe in my 5153, I hope the Cpig helps here.
