Hi,
 
As you will see from my profile picture I'm missing 2 original Alembic Essence tuners, furthermore the 3rd one is also broken and I'm in need of it. So altogether I need 3 Essence tuners and need someone to help me out here. Have you got any spare items to sell?

You probably need to call Mica and order a set of gold Gotoh (Spelling?) machine heads with the Alembic logo on the back.  They still come with the 'A' don't they?  The model of bass does not matter with these, BTW.  FYI.
