Hi,
This is prototype.
I got a same shape bass (small head with tuner, convensional bridge, long upper horn) as Junk.
Activator PU and circuit are on my Hamer B12-S at now.
I know this bass still on the wall of the music store (the shop name is shown "TC-GAKKI" under the photo).
Other Alembic basses that the seller listed are for sale at another shop.
I think the seller will buy it when someone bid and win the bass.
