I have an '84 Exploiter, my first Alembic and still a blast to play. I have the original case, rugged, one broken latch, but still functional.
The challenge has always been transporting it. I drove a Mustang rag top for a long time, and the only way to get that case in the car was either drive with the top down, or rest it across the passenger rear seat and the passenger headrest. Of course its not secure there, and I dang near killed myself turning right and having the bass and case smash into my right temple!
The body shape and overall length prevents you from getting a smaller case, and a new case is typically $400 plus because of the size. So what's a player to do?
Well, Dean has out a series of low end basses (Metalman) that have Z and X shapes, and they offer a large gig bag that fits those shapes for about $65.
Let me stop here and say I am the first to advocate the use of hard shell cases, and gig bags are not a substitute for a good case, BUT sometimes someting smaller and more convenient for local transportation in your car is helpful.
I recently bought one and it fits well. I haven't had it long, but the quality seems decent for the price and its definitely made it easier to take along for local sessions.
I'm sure it's not for everyone, (and you are putting your Alembic in a bag marked Dean - makes it less likely to get stolen ), but if you're an Exploiter owner and you've ever wished there were an easier way to shuttle your baby around, you might want to check it out.
