More work involved = more money paid.
The deluxe has both front & back matching woods whereas the standard only has the top wood with accent laminate and body wood.
With Alembic you can start with a 'basic' model and if your wallet/bank account/inheritance/mortgage(whichever is easier!!) has the funds you can add as many custom options as you want.
Multiple body laminates, multiple neck laminates, ultra exotic woods, LED's, gold hardware, elaborate inlays, custom electronics.
All depends on your imagination and how much money you have.
