I've got 6 LTD's in my rack right now - 4 of the 87 Series and 2 EC-1001T's. Only on had issues - an 87 Series M1 - it was neck-thru, and in order to get the action where I wanted it, the trem was decked (and then some), and the fingerboard was completely flat, so I was getting fret buzz all over. I returned it yesterday - it was one of the GC.com used buys in "Great Condition". I told the guy working the counter about the issue and that they ought to have their tech see if there's anything he could do. He said "We'll just put it on the wall, and someone else can have the problem"... Lol...SMH...
Anyway, the fretwork on all of these guitars is TOP NOTCH, and not just for the price. The necks are really exceptional on these guitars, and definitely the selling point. Good hardware, tight tolerances, and quality finishes. I had 3 EC-1000T's about 10 years ago, and traded them away, and that was one of the few trades I really regret. Other than the one guitar I mentioned above (which was MIIndo if that matters), I haven't gotten a turd.That's probably out of 20 or so over the years.
