What makes a Double bass good for Jazz or Classical?

[Sercan Say]

I dont have dimensions but I'll try to get them.

I understand sound issue, I think final setup and strings are effective in this issue.

This bass has one problem too, when we hit F# on the E string with pizz. suddenly volume decrease and then increase.We cant solve this problem.I will put some pictures and maybe some sound sample If I can

Recently we built 2 other bass too they have nice sounds pizz. and bow as you say.
