The "top-of-the-shelf" stuff such as pre-CBS Fenders, certain Ricks, '60s ThunderBirds, Wal, Alembic is likely to stay on the expensive side.
Other gear will eventually drop in price, since less people seem to have disposable funds for vintage stuff, and those who do want the pieces that I was referring to above.
That's a very pretty instrument you have, but an EB-2 is not an easy bass to sell. Never was. It's not even a matter of price in most cases, you just have to bump into someone looking for that unique appeal that these instruments have.
I was lucky to find a buyer for my '68 two years ago.
Good luck.
