That is indeed an Alembic in the middle, Exploiter body style as they call their spin on it, officially a "Spoiler" model. Bought it used, I think it was from Club Bass in Canada. Serial dates it at 1985. I was actually looking for one that looked more like Entwistle's, always loved the way his looked and his Alembic sound. This one turned up a good bit cheaper than any other I'd seen. It's not really much like John's, being the budget model (HA!) but the 32" scale suits me better and the dumbed down electronics are versatile enough. Neck is thicker than I like, and the design pushes the nect forward if you will, so that it's easy to play high fret positions but the lowest are a reach for a Hobbit like myself. Once I plug it in, though, the sound is worth it. Just got it and my Mouradian CS-74 back from Mouradian Guitar, and the Alembic finally has action low enough to make me happy. The CS is my favorite when I'm playing it, too, but I don't want to spam pictures of all my junk so I settled for 1 pic with 3 basses.
You can definitely (should definitely!) post pics of the Mouradian! I used to get my basses adjusted by him in Cambridge, Massachusetts. Including an '85 Spoiler/Exploiter, but not as unusual as yours!
I'm going into the studio this week - first time here in California! - and my car isn't that big, so I have to choose carefully what I am going to bring. It basically boils down to my favorites, my '76 Rickenbacker 4001, '03 Alembic Stanley Clarke Signature Standard 5-string, and I'm going to use my '68 Melody Maker Bass for the first time in a while too. It's just me and my drummer, we'll be doing our usual improv thing, but I think I'm going to record some covers for the first time in eight years - Slim Harpo's "I'm a King Bee" and "Come Together" by the Beatles. I don't see much point in recording covers - not sure about all the legalities - but these have emerged as possibilities. The Beatles tune will probably just be for my own use (karaoke anyone?) but we'll see what I can do with "King Bee"...
This shot was taken while performing "Come Together" at a recent Rickenbacker gathering - I can tell because the neck tone knob is turned all the way down:
This Ric was one of the first basses I bought when I got back into music in 2002 (after an eight year absence) - the first was actually the Exploiter I mentioned:
I've since sold the Exploiter - just wasn't playing it enough, plus I kept banging the lower extension into doorjambs!
