The hardware on Agile guitars is junk. Pickups aren't anything to write home about, either. Build quality is sometimes hit-or-miss. Check out the the Electric Guitars section of the forums at Harmony Central. You'll see mostly praise because they are decent guitars for the money, but you'll also see a fair amount of "WTF?" type threads where somebody bought an Agile and received an unplayable piece of crap.
To be honest, Epiphone build quality is better than both Agile and Gibson these days. They have better hardware, fretwork and detail (binding, etc) than the Agile's and are more consistent in build quality than Gibson. They cost more than an Agile, but then, you get what you pay for. Epi's used to be crap 10 to 15 years ago. They've come a long way since then to become one of the best guitar values on the market today.
