Hey Greg,
So close together, our basses. Your bass has a nice top on it; bet it sounds great. Mine has built-in fingerboard relief from the factory, kinda like camber on an upright board, I suspect, that works for dry and wet climates. The truss rod is only for function if needed, which is never. Incredible build quality from the earlier days of Alembic. Original frets on mine, and Ron has gone through it with no need for an upgrade.
