Spotted this one on eBay and won it - my first auction win. Over time, I uncovered more information about it - it’s a “production custom.” At the time, licensed ESP dealers could request a shipment of guitars from ESP with some custom options that differed from the catalog models. It’s not exactly custom shop, since several guitars would have to be ordered - which probably means there are a couple of similar ones to this out there.
Still, a Maverick Deluxe, with no pickguard, and a figured maple top is a heck of a guitar and in hindsight, I got an incredible deal on this beast. I replaced the factory humbucker with a Dimarzio D-Sonic which sounds great in that position, though I still have the original humbucker as well.
