I'm with Alan on the Lakland. Their quality is consistent. There are nice Jazz Basses out there, but the production of those has never been nearly as consistent as Lakland, or, say, Rickenbacker (at least in my experience). The Conklin 7-string I owned was very, very nice. Steinberger L2A is a consistently sweet and very even bass (that could really use Alembic guts). Oh, and don't leave Carvin off that list. Love 'em or hate 'em, they are a very well-conceived and well-executed bass guitar.
Now, if we're talking about instruments that *inspire* like an Alembic does, then the Rick Turner Renaissance or some of the Warrior basses do it for me, big time, but for reasons I can't explain..
