I started out on a Gibson J45 with a national neck. I have been looking for a similar sounding guitar for years, full and mellow. I picked up a brand new J45 in a local store. It sounded well unbalanced and very harsh. Not the same at all. What a disappointment. So much so I asked my luthier friend to spend the effort to rebuild the old guitar. I named it Frankenstein. I suppose it is more so as it will be getting a new top.
