Input impedance is 1 megohm, so it should work fine with your double bass set up.
Hope this is helpful!

I would be happier with maybe 4.7 megohms like the ParaDi,
or even higher (10 megohm) for the Piezo's.
I'll still use the Hammer for electric bass and see how it works
for the upright. I'm hoping for a pleasant surprise.
