Just checked the Craig's list picts. This doesn't have standard Essence electronics, perhaps another group member can identify them. However, the neck-through construction, the gold hardware, the fretboard with no abalone ovals--those are all standard Essence features [The Epic, a lower priced model, has a bolt-on neck.].
Pricewise, $2500 seems a bit steep to me, though it is a nice looking bass.
