I recently had the chance to spend some time playing a couple of extreme high end basses - a 70s Alembic and a more recent Fodera.
They're often mentioned in the same breath but the only thing they really had in common was the sheer quality of the instruments.
The Alembic looks and sounds like nothing else, everything about it is making a statement. The Fodera in comparison is very refined in appearance and tone, undoubtedly a class instrument but a bit too polite for me - there was nothing that shouted "this is the Fodera sound", unlike the highly idioyncratic Alembic. And the Fodera neck was too slim for me but that's just my preference.
