Thoughts?  Seller claims it is all original Alembic.  I doubt it.

Hard to say without seeing the lookup. I don't see any red flags. Looks like a Spoiler shape fretless with Excel electronics, basically.

It looks like it's set neck.  And the tuners are not original.  And the pickup covers?  And the gloss (I assume epoxy) fretboard?

Looks like a neck-through to me, but none of the pics show any of the back to be definitive.   Vermillion is one of the less often seen tops.  This one sure is purdy!

Bill, tgo

There is a shot of the back.

I knew we'd seen this one before on the forum.

Looks legit to me. Really cool array of custom features, but I don't see anything that Alembic would/could not have done. Set neck and wood pickup covers are available options. Can't say for sure on the shiny fingerboard.
