Hi, I just purchased an 1989 Alembic Spoiler from a private collection. Details are a bit worn, so I am not sure I got the whole range right.
Top is definitvely Q-Maple, maybe that helps identifying this 4-string Spoiler.

Welcome aboard!
 
if the details are slightly worn posting a picture of the bass can help clarify things (and appease the picture loving Alembic owners).

L.A. would be USA ;-)
Pictures are more than welcome!

Howdy!! Well, that's funny...I got this one :-)

I'll post better pictures shortly
 
Cheers,
Mich

Congrats! That's a nice one, glad you bought it...now I can sleep again :-)
 
Welcome to the club btw!

Ahh! removing the backplate reveals the serial number too. 89s5326 it is!
