2011 Epiphone 339 Cherry

I bought this used stellar Epiphone ES339 in 2017 and upgraded the pickups to Seymour Duncan Humbuckers, Gibson pots (500), Gibson knobs and wiring, and new locking tuners. It is essentially a Epibson or a Gibiphone. It also comes with a new Epiphone 339 case. With all upgrades, this guitar should sell for $1,000. However, only asking $550. This price is firm and not interested in trades
