Re: Checking legitimacy of a Les Paul.
Ask the dude for clearer, sharper pics of the whole guitar (not just front). That pic is somewhat blurry.
Also, I'm not sure, but the reflector knobs tells me it's a 60's or 70's tribute les paul.
And looks like a mini in the neck... which further leads me to believe a 70's tribute les paul
...and he put a humbucker in the bridge
