Re: Fender Wide Range HB's vs Gibby HB's
You probably won't notice any difference. Assuming you have a reissue, it's not like Fender is filling up the extra space with lead (FYI it's waxed string).
If it's just too heavy there isn't much you can do. People drilled out a bunch of Swiss cheese like holes in a guitar with nominal difference. So sans chambering the whole thing, just get a wider strap, replace the body, replace the guitar, or just deal with it.
