Just bought a 2018 advanced Jumbo limited. For the life of me, I cannot seem to figure out what made the "Limited" different than the standard re-issue. Not even a call to Gibson customer service helped. All I know is that 35 guitars were made for this limited run. Nothing about wood, construction, cosmetics. Love the guitar! Just seems kinda silly to call something a limited edition if in fact its identical to the standard model. Anybody know any different? would love some real info.
