I got in an brand new Eclipse II recently and it buzzes pretty badly as well. When I asked the ESP warranty guy about it, he told me that Eclipses buzz.
He even checked my neck and said I got a good neck...nice and straight.
nice to know that AFTER I buy a Brand New GUITAR!
Here's a question...
do the older models, or Full Thickness Eclipse models sound...THICKER?
I find my Eclipse is very thin sounding compared to my other guitars (currently at 12). I don't think it is the EMG's...just seems not to have as heavy/low/deep of a sound compared to my Gibson, or any other brand guitars.
Since it is a clone, i thought it would sound fuller....
and yes...my string buzz buzzes through the amp as well, but not that bad.
