My 55-02 has plenty of punch! It really depends on your string choices, EQ and PU selection, and playing technique. Also, it can be as aggressive as the rest of them, you just have to know how to get it out of the bass.
With the switchable mids (inside cavity), You can get a wide range of tones. It depends on what kind of tone you want, heavy and supportive or brighter and snappier. It's all in the bass.
It does have a gain control inside of the control cavity. I'm not sure of the exact amount of boost it gives, though.
Most people who claim that the 55-02 is too tame simply haven't taken enough time to really learn how to get "their tone" out of the bass. It's all there, you just have to squeeze it out.
