I know the original intent of the maple cap was to brighten the tone a bit, from the darker sounding Mahogany. Many agree this does occur. Some differ, I think Big Al represents those who feel there is little or no real difference (chime in Big Al if I've mis-stated your position). I'm curious what others have to say. I guess the test guitars would be 50's GoldTops vs. Customs (or the modern versions).
