Re: ESP and Edwards guitars
i have ECY130D, pretty much the same with ECY165.
27 fret with 25,5 scale, the neck feel almost the same with WII Ibanez, only the satin finish on the ECY is somehow 'softer' than ibanez.
the ECY equipped with original floyd rose, make the tone more tight than with any edge/lo pro/ edge pro whatsoever.
the duncan TB5 on it is bassy, not aggresive enough, the cool rail on neck is OK.
maple top is only a veneer, not real wood.
overall : it's a good one, I think every RG player won't find any difficulty transition to the ECY, it's not built for metal, unless you want to change the TB5, it's too 'wet' for metal IMHO, but it's one kind of thing that shredders will look for. 27fret, fast neck, whammy bar.
