Sorry to say man... I think the small similarities are coincidental... I highly doubt that they based this controller off any vintage guitar that isn't a Gibson or Epiphone... The only Epiphone I've ever seen that even comes close to that is a Crestwood... and it's not even close to that...

Either way, I don't think that the controller is based off that guitar. I think it's just a random guitar design that bares a small resemblence to a vintage guitar like the one above... The JET KING doesn't really look like it after I put them side by side... I still think it's some old Yamaha.... maybe an old Gretsch... who knows... I've invested too much time in this, I just realized that I don't even care.
