Paasive or Active for high pass filter?

[moltenmetalburn]

I want to experiment with outboard high pass filters similar to the Ayan slim n smooth. I plan to try the unit in front of the amp and also the effects loop. I m not sure whether to begin with a passive or active design.

do passive high pass filter incur a signal level loss other than the bass being filtered away?

My thinking is to remove any low end below the fundamental of my root, and also experiment with removing everything below the second and possibly third harmonics of my fundamental.

Any advice is welcomed thanks!
