I've seen several reviews of the Epiphone ES-335 and all seem to be in agreement that it stands up well to the Gibson version. I've not played a Gibson ES-335,so I can't compare directly, but... this is a great guitar. Well made, impressive weight, and with the action suitably lowered, plays beautifully across the neck. The pick ups are loud (!) with impressive amounts of sustain, and around the 10th to 12th fret, there is a very familiar ES-335 sound.
There was a big red notice on the guitar bag that said "Attention! Valuable and Important Accessories in Box. DO NOT DISCARD!!" I was excited to discover it was a square of 'Mini-Air' bubble wrap (recyclable) and a custom-made round foam protector for the pick-up selector switch. I will treasure them.
Anyway, at this price, a left-hander who dreams of an affordable ES-335, really should pick one of these up. It's a joy to play.
