The model of that guitar is in fact still up on the ESP website! My guitar is not a custom job; it's exactly the model and specs you would get off the rack. You are right; the guitar is very versatile and can cover all sorts of tones from softer to heavier, and is one of the reasons I love it!
Also, the PC1V and PC2V have slightly different body shapes from each other. But I think that's really the only difference.
Keep rockin!
