Re: Gibson Les Paul 'Black Beauty' Mod Custom 1980 - modded with Floyd Rose - E.M.G 81/85
In good unmodded condition, I'm guessing that guitar would be $1500 - $2000, I like those years because of the white instead of cream binding.
With the mods that have been done to that one, it's no longer a Les Paul to purists, especially the floyd. I probably wouldn't go ove $600 - $800 for it if that much because I would be worried about resale value.
These are only my opinions, so definitely do some research. Search completed items on de bay, especially look for ones that have been modded. For better or worse, that has become the best place to look to determine "market" value of items these days.
