I've been wanting to try one of these guitars for some time but before I jumped in and bought one I thought a little bit of background on them might prove valuable! Is there any particular "era" of them that could be termed the best? By that I'm referring to fit/finish, overall build quality and even their tonal characteristics? I know the early ones used Lace p'ups and now they are using their own vintage noiseless p'ups. Do most folks have a preference? If I were to get one and didn't like what was in it, could they be replaced with Lollars or Fralins and still have the boost circuit? Any comments/suggestions appreciated!
