After hitting up the EB forums, I found this clarification from one of the mods:
"The "Classic Collection" Sterling Bass (made from 2010 to 2015) has a Ceramic pickup wired in series (not parallel). It has the same 2 Band preamp as both the "Classic Collection" Sting Ray 4 and Sting Ray 5 which both have Alnico pickups BUT wired in parallel (and not series). The 2 Bander is the same preamp used on the Sting Ray since Pre-EB 1978. The bodies are slab.”
