i don't have the intention to dive into a doen't-does-doesn't-does discussion. That would be pointless. It is YOUR feel and experience with the bass and I have a fully respect for that.
Though that experience and feel is worth anaysing for the sake of your playing eagerness.
There was once a statement of our Brother Joey that said playing Alembics with the original designs (Standards and Small Standard)asks for some learning.
I suggest that you hold your bass with the strap attached only on the upper horn.
How does it balances? On a wrist-watch lay-out (and for a right handed bass): does the neck pointed 1hr? 1:30? 2?
Alembics seldom (maybe even never) dive in the sense it goes to let say ...huh 3:30hrs.
However!
You can FEEL it as a dive.
Like I said earlier in other threads: the neck position of Standard Alembic shapes versus YOUR body is radically different than any other bass you played. The neck as a whole is situated more to the side of your body. That will result in a need for more reach.
The Alchemy bass here
is a Series II Standard shape 5 string with a 35 scale.
Go figure the arm-reach you need!
Though I refer to Brother Joeys statement: it needs an attitude to play those old designs.
I am 1.90m tall and I have no problems.
Our brother James (Mathumb)is Black short and handsome (that one still makes me laugh) and still a Series Standard body addict.
SO we both manage that reach and ...to be honest...I don't know how I do it but it is ...well ...huhuhuh...different??? THan the other basses I have.
I agree that Alembic more recenter body-styles are giving more playing comfort for those who are used to fenderish styled bodies.
But I wouldn't use the word dive for the old Alembic body styles.
Just some thoughts.
