I'm sure the pickups will probably be really weak. I bought a gain booster for one of my guitars on ebay, and it worked for beefing up the sound (After changing the pots it sounds pretty close to my EMG Kerry King setup on my LP) Can't afford to buy a ton of guitars and then swap out all the parts - it would be cheaper just to get one decent guitar as the cost of pickups, bridges, pots, nuts starts to add up, not to mention the trouble of replacing them all. But if your EVH ends up being a decent guitar though, then I guess it would be well worth it.
