Hi Jason, great to see you here again :-)
Alembic did runs I think, the early Spoilers were all (?) with solid Koa bodywings and I guess the Distillate was also some sort of production model.
If I'm not mistaken, they made lots more Instruments per year in the eighties than they do now.
I looked at some serialnumbers and think they did about 300/400 instruments in '87 or '88 against less than 150 in the last few years...
The bass above looks like a Europa bodyshape + headstock and Essence electronics.
Model name: JNLSB (Jason Newsted long scale bass)
The back of the neck is finished black (not clear like Jason's basses) and I doubt if it has the transparent black color option (on my quote it says Sheer Black finish clear satin back of neck Jason Newsted style)
I'm going to have the same finish as on Jason's basses and o boy, that's a serious investment ($$$!)
I can easily have my house painted for that amount and it was a real shocker, but I'm sure it's going to more than worth it
(and will be done with a lot more care than my house)
Also there seems to be no PH neck lams, looks like walnut veneers to me.
If this is a Jason Newsted model it would be in the same line as the signatures: an affordable look-alike of the real thing.
Is there a serial number mentioned?
I'm eager to see what Mica has to say...
