Double Bass K&K Bass Max - quiet higher register

[Michal Herman]

I have K&K Bass Max pickup on my bass. I know. "Bass Max".
I noticed, that higher registers (above C on G string) are much quieter than lower registers on pickup signal, but acoustically they are on the similar level.
Any tips how to give a "punch" to upper registers? I usually play in lower registers but on gigs I sometimes do melodies on upper register and these are noticeably lower in volume.

I'm afraid it's a pickup limitation.
I'm pretty satisfied with the Hurley single shot wing pickup and it's half the price of the Bass Max.
Balance across strings seems very good to me.
(and I had Bass Max pickups in the recent past)
