What makes a Double bass good for Jazz or Classical?

[quote=Pongsak Sooksawak;4073]That why my bass has a very strong upper and moderate bottom. Also, My baby is so heavy.

Plus, the shape of your bass prevents it from being deep-sounding. Generally, basses with small, sloping shoulders (regardless of the lower bout size) have a penetrating sound, but little in the way of bottom.
