I haven't tried many ESPs, so I could be wrong, but it's not just the (to me) skinniness of the neck, the whole neck shape just doesn't feel "right" somehow.
Same with most Korean guitars I've tried actually (are LTDs still Korean?), I know lots of different Korean brands are built in the same factories (like the Cort factory), maybe those "factory" neck shapes just don't suit me? :lol:
