Fixed it for you. Stingrays basses are active. If you put a battery in the bass to make it work, it is an active bass.
When I spoke to EBMM customer service, I was kindly informed that the American SUB's were manufactured in the same San Louis Obispo plant and are modeled after the Classics (slab body, sustains for dayyyyyys!!), use poplar instead of ash for the body wood, and have the "custom" textured finish and black satin finish on the headstock/back of the neck. The stock pickup and electronics (if they're active) are also the exact same as "real" 'Rays and are internally wired in parallel.
....Oh, and the aluminium pickguard.
You either love or hate the pickguard. It's about 1/16" thick and quite flimsy feeling. I personally don't mind it, and has inspired me to style mine in an industrial sort of theme. if I could only find some Ric-style knobs (like pictured below) that don't say "volume" or "tone," and completely blacked out hardware, I'd be set. I'm also really glad that the body isn't routed for wiring like a lot of P-basses are, so I can rock it without the pickguard for that oh-so-sexy G&L look.
On the topic of black hardware, I was thinking about getting my existing hardware coated in Cerakote, typically used for coating gun parts. I saw a video on Youtube of some dude who did some other dude's Stingray parts and they have a super sexy matte black finish to them. I'm not a fan of shiny, so this really got my interest and have been trying to find a Canadian shop that would do it for me. Topped off with an OBP-3 preamp, and it's gonna sound massive.
Back on topic, the point I'm trying to make, is that if you find one of the USA SUB's, buy it, buy it fast!!
