gibson made some explorers and vs with alder/maple set neck construction in the 80s - I think 83 was the big year for that.
this is a special edition model i have seen before - it was in gibson catalogue and is an offical model. shame they didn't do a v one.
i would totally play this guitar, but i won't be buying it - because i don't have anywhere near the money, its priced way over the odds, and even if both these factors were sorted i'd be thinking of a V XPL.
would quite like a swamp ash or alder v.
