The 339 is a keeper for me. When I'm longing for something Gibson like the 339 delivers. I love the quality and variety, plus it is a trusty backup guitar. Being a Strat guy through and through, I really fell in love with the smaller body and the smaller neck dimension of the 339. Further I proudly play an Epiphone to tame all the cork sniffers ;-)
Of course I was kidding with the cork sniffers...in the end the beautiful quality and the inspiration this guitar gives me makes it a fix part and fallback in my setup.
