What to say, this 339 sounds wonderfully, just like the real thing...
I own both a Gibson 335 and an Gibson ES Les Paul, and the quality of sound is at that level.
Under an esthetic point of view, the instrument is nice, good painting, no issues.
Regarding the playability is good, even if this aspect is the one different from the Gibson “touch and feel”. I’m not surprised of course, this guitar costs a fifth of the Gibson version, and somewhere the savings have to be gone...
But, to be honest, this guitar is great for not professional guitarists, and it’s good for advanced ones too.
This guitar becomes a little less comfortable playing, for example, Donna Lee at 230 bpm, but not everyone has this need...
