I'd give the fit and finish 5 stars, the unplugged sound a 3, the plugged in sound a 4, and playability a 4.
The guitar looks beautiful. No imperfections after a thorough inspection. The color is a nice tan/light brown and is very pleasing. I would prefer a little darker, but it still looks beautiful. The finish on the neck is perfect. Enough tackiness to hold your position for bar chords, yet smooth enough to fly up and down the neck.
The sound unplugged is boxy and not as clear as I would have expected. Compared to a 20 year old fender dreadnaught (laminate sides and back, solid spruce top), it sounds boxy and not as rich. The individual notes of a chord become muddled together, when on my fender they are crisp and clear. I am hoping this changes as the wood ages.
The plugged in sound is very good. Has a variety of tones from the two pickups. The nano flex tends to dominate the sound when the blend is used. I have to slide the blend nearly to all nanomag to get a true blended sound. The nanomag is much quieter in the mix than the nano flex. The nanomag caters more to the bass side of things where the nano flex picks up the treble sounds. I have used the nanomag with distortion and it is surprisingly good. No Les Paul mind you, but would be serviceable for some classic rock tones from an acoustic. My two gripes about the esonic2 are the nano flex dominating the "blended" sound and a slight popping when finger picking. The electronic pop is annoying when playing softly, but is not audible when strumming or picking with some force.
Playability is great. The neck finish is smooth enough to fly up and down the neck, while still tacky enough to hold your position for barre chords. It was plek'd and I do believe this helps with playability quite a bit. Two complaints here are the action is too high. Haven't measured it yet, but it certainly needs to be lowered at least 3/64, probably more. The other problem is the 15th fret needs some dressing which I thought the plek'd process would have addressed. It makes bends at this fret difficult. Lowering the action and dressing this fret would make this a 5/5 stars.
Overall this is a nice guitar. I will probably keep it. It's the first new guitar I have purchased since my first Peavy kit 25 years ago when I started playing. I am a fan of Epiphone having a Les Paul Standard that is as good as any guitar I've every played (now that I've set it up properly). I wish the unplugged sound was more crisp and clear, but I purchased it largely for plugging in. Epiphone makes great affordable guitars.
