I'm looking at buying a new bass for my church (one of these days, I've been wanting to do it for months but still don't have the money

)
I'm going with a passive bass, they're tired of batteries so I think a good passive bass would be a real blessing for them.
Right now we're using a passive DI box for the church bass. Pretty simple one, has a PAD switch and a ground lift, 1/4" in and out, and an XLR out.
Do you think the bass will suffer too much treble loss if it's plugged into that box? If so, do you have any recommendations for one that won't?
