Double Bass Impedance mis-match question

[RockinBones]

I've just started playing double bass in a band for the first time, but in the practice room we're using, I'm running my bass into someone else's amp (an H&H 100w bass combo). Now, I have a K&K bass max, run through a Behringer BDI21 pre (not great, but £20 and should knock the impedance down from 1m to 1k ohm). And the sound I get is rubbish - really treble, really quiet, feeds back at audible volume.

So this sounds like what everyone says about mis-matched impedance, but I've run the same setup into my Hartke 500w and it sounded cool - plenty loud and deep.

So is it most likely that the 1k ohm output is still too much for the H&H? Or could it be something else? Thanks!

The manual specs the input impedance at 1Meg, which should be just fine. If the pickup is not defective and is installed properly, my guess would be that the B is just not well suited for use with something that you want to preserve the tone of.

The first time I heard a BassMax it was through a Radial Pro48 (which I think is only 100K). It was not particularly "woody", but it was smooth, articulate, and went very deep - I liked it a lot.
