^I remember seeing that guitar. IIRC, someone on the
ESP forum at that at one point. I remember because it had been routed for a neck SC, and they used that (IMHO) ugly pickup ring.
Unless you've for sure seen a battery in the control cavity, that wouldn't be an active pickup, and if there is a battery I'd still be skeptical that's it's for the pickup...Could be for some type of boost or something.
because of the non stock condition with the route for the neck p/up, I'd be curious as to the value of the trade. No doubt they are killer guitars, but they usually don't fetch a lot on the used market. I'm almost positive this sold for around 400-600 bucks on the ESP forum though. But that was a few years back.
