Perhaps "convert" is not the correct word, but you know what I mean! I am buying a Gibson Thunderbird IV, and would like to know what I need to do to make it work. Is it fairly simple? I know the nut has to be set up for it, but do I file it or buy a new one? Also, I am wondering if the pickups are designed to "pickup" notes that low... Thanks in advance for the help, guys!
