I got confirmation today that I can use my gift certificate towards this bass, so I went and checked it out.
Very first impression: it's small! For some reason, it looks HUUUUGE to me in the pictures. It's actually small and graceful compared to my Jazz bass.
The shop kindly removed the covers so I could inspect the electronics (including battery compartment) and truss rods. I'm no Alembic electronics expert, but it looked genuine - a tidy little circuit board, modular connectors, no cheap CTS pots. The truss rod nuts turn, the neck has reasonable relief on both sides, so I'm assuming everything is working fine there.
I played it for a while. The filter took just a little getting used to, but with that and the quick bass/treble switches I was able to find some good tones quickly. Lots to explore there! It was set up decently, although I'd probably want to tweak it to my taste.
I noticed one thing that I'm hoping someone can give me some perspective on. The neck is three pieces of maple separated by thin veneers of some dark wood. I was surprised I could feel these seams through the finish. Is this normal or is it a cause for concern? It felt very uniform the entire length of the neck beam.
Because I was only able to get to the shop about an hour before their closing time, I didn't feel like I'd had enough time with it to commit to buying it. I told them I'd sleep on it.
Thoughts? I'm inclined to buy it (unless someone tells me the neck is probably coming apart), on the theory that any Alembic in my hands (even if it's not exactly the one I thought I was looking for) is better than a thousand pictures of beautiful but ridiculously overpriced Alembics on Reverb.
