First off let me say I love my 335, it's my main guitar and its my fav in my collection. However I was very disappointed by a few things.
1: The case is terrible, Absolutely rubbish quality and mine broke within the first few days, I didn't even put any stress on it, it was on my couch and I noticed the bottom had completely caved in... shockingly bad quality.
2: After a few weeks playing with it I noticed something white in one of the soundholes... the builders left a big piece of paper from when they painted it I assume... I mean this thing is almost 2500 euros that's shocking.
3: I also noticed a white mark on my fretboard which I tried to wipe off but it doesn't come off, it's a defect or some glue left over, I don't mind it too much but it's quite big and also very shocking for the price.
4: The tuners... I swapped them... just absolute garbage. One of them wasn't working properly.
Another thing that surprised me is when I received my Epiphone 335 and to my surprise its was insanely good. The tuners are better, the pickups are good, it was set up well and no faults in it. The sound to my ears is as good... and this is a guitar that cost almost a 5th of the price.
Want my opinion, get yourself an Epiphone... like I said I love my Gibson but these days its not worth the price and you'll have to spend more on a new case and tuners.
