1970's Vintage Custom Made Electric Guitar Solid Burl Neck Thru Alembic Unique  
 
It does look like a 70s-era hand built instrument, but that doesn't make it an Alembic...  I doubt this is even a shop-night guitar.

I know the owner of the store and have handled this guitar. He is a good guy and I am sure there is no intent to fool anyone. It is not an Alembic. It is pretty thin and light and seems well made.

The shape of it reminds me of Brian May's guitar.
