Hi Pierre,
Yes, I am the member of japanese Alembic Fan Club. (There is the link to gallery page in my profile.)
I started to play my Dis-B from 1981.
I am not professional player in my carreer, but I continue to play bass with several amateur projects.
In fact, Now I own 7 Alembic basses.
But these are never in closet or under my bed, all basses (also Turner Model-2 bass,PRS fretless, Hamer B12S) are ready to play anytime.
I choice the bass which do I like better at the point (I can say in other words boom), or which the sound better for each song.
Each Alembic basses has each tone and playability.
I am very interested How about the difference another one.
So I'm still seeking best one. (but only one)
I surely said this bass is the best of one side. (I don't know how many sides are.)
Eiji
